Language & meaning
Meaning & Irish forms
Gaelic Gaelic Irish, from two separate septs (Ó Riain of Carlow and Ó Maoilriain of Tipperary and Limerick) whose names merged in English as Ryan.[1][2]
The name is built on the personal name Rian (Riaghan), usually explained as “unknown”. Wikipedia cites Edward MacLysaght and the historian John Ryan of UCD. Both say the meaning of Rian has never been explained. Scholars reject the 'water' and 'king' etymologies, and 'little king' and 'illustrious' are popular modern guesses with no scholarly support.[3]

Origins
Septs & territories
Many Irish surnames were adopted independently by unrelated families. These are the distinct Ryan lineages described in the sources.
A surname can point you towards a place. On its own, it cannot establish a pedigree.
Ó Riain of Uí Dróna
Uí Dróna, the barony of Idrone · Carlow
Woulfe describes this Carlow family as lords of Uí Dróna, now the barony of Idrone, and says the name had become numerous throughout Leinster. Idrone was later split into East and West baronies in 1799.[1][6]
Ó Maoilriain (O'Mulryan) of Owney
Uaithne-tíre and Uaithne-cliach, now the baronies of Owney (Tipperary) and Owneybeg (Limerick) · Tipperary, Limerick
According to Woulfe, this family was of Leinster origin and settled in Owney in the 13th or 14th century, where it became numerous and powerful. Wikipedia notes that it displaced the Ó hIfearnáin family there. Woulfe found the name very common in Tipperary and Limerick, usually shortened to Ryan.[2][7][8]
The name over time
History
Two families, one English name
Ryan is a merged name. Woulfe separates the Ó Riain of Carlow, lords of Idrone, from the Ó Maoilriain of Owney in Munster. He warns that the Munster name, and the Connacht name Ó Ruaidhín, had both come to be written O'Ryan or Ryan. Woulfe takes Ryan as a clear example of a name cut down during anglicisation: only the last part of O'Mulryan survives. The Mulryans and the Carlow O'Ryans are therefore not one family, even though they now share a spelling.[1][2][9]
The O'Ryans of Idrone
The Carlow family took its name from an ancestor called Riaghan or Rian. Its heads were lords of Uí Dróna, a territory that survives in the name of the barony of Idrone. Wikipedia's articles on the two Idrone baronies, East and West, which were created when the old barony was divided in 1799, record the O'Riain sept as lords of Idrone. By Woulfe's time the descendants of this family were spread widely through Leinster.[1][6][10]
The Mulryans of Owney
The name Ó Maoilriain means 'descendant of the follower of Rian'. Woulfe says the family came from Leinster and settled in Owney in the 13th or 14th century. That territory is now the barony of Owney and Arra in north Tipperary and Owneybeg in east Limerick. There the family grew numerous and powerful, displacing the Ó hIfearnáin. In 1610 William Ryan surrendered his lands and rights in 'Owney O Mulrian' to the Crown and was granted them back by letters patent. The lands were lost in the 17th-century confiscations. Wikipedia says the family held Owneybeg until the Cromwellian conquest.[2][7][8]
What does Ryan mean?
The honest answer is that nobody knows. Wikipedia cites Edward MacLysaght and the UCD historian John Ryan. Both say the Rian in Ó Riain and Ó Maoilriain has never been explained, and that the name seems to be so old that its meaning was lost before records began. Some have linked it to Old Irish words for 'water' or 'king', but scholars have discounted both ideas. The often-repeated 'little king' and 'illustrious' come from popular name books, not from scholarship.[3]
Other Ryans
A few Ryans come from neither main family. Woulfe records that the Connacht name Ó Ruadháin or Ó Ruaidhín, usually Ruane, was sometimes 'disguised' as Ryan. In County Mayo, the Donegal name Ó Sraitheáin was occasionally given as Ryan. In the United States, Ryan has also been used as an Americanised form of the German surname Rein. For a particular family, the county it came from (Carlow, or Tipperary and Limerick) is often the most useful clue to which line it belongs to.[4][5][11][3][1][2]

Heraldry
Is there a Ryan coat of arms?
There is no single Ryan coat of arms. Arms were granted to particular families and individuals, not to everyone who bears a surname. Because Ryan merges at least two unrelated Gaelic families, a 'Ryan crest' sold for the surname as a whole makes even less sense than usual. None of the sources used here document arms or a motto for a named Ryan sept.[1][2]
Websites selling a single “Ryan family crest” are selling a design, not an inheritance. Arms in Ireland belonged to individuals and their heirs, and the Chief Herald of Ireland still grants arms that way today.

Questions
Questions about the Ryan name
Is Ryan an Irish surname?
Yes. In Ireland, Ryan almost always comes from one of two Gaelic surnames. Ó Riain belonged to a Carlow family who were lords of Idrone. Ó Maoilriain (Mulryan) belonged to a family that settled in Owney on the Tipperary–Limerick border. Both names were reduced in English to Ryan. Outside Ireland, Ryan is also popular as a first name, and in America it can be an adapted form of the German surname Rein.[1][2][3]
What is Ryan in Irish?
The usual Irish form is Ó Riain (older spelling Ó Riaghain), 'descendant of Rian'. Many Tipperary and Limerick Ryans, however, descend from Ó Maoilriain, 'descendant of the follower of Rian', whose name was anglicised Mulryan before being shortened. Both Irish names share the same obscure element, Rian, but they belonged to separate families in Leinster and Munster.[1][2][3]
How do you pronounce Ryan?
In English, Ryan is pronounced 'RY-an', rhyming with 'lion', and O'Ryan is 'oh-RY-an'. Mulryan keeps the same ending, 'mul-RY-an'. The English forms come from older Irish spellings such as Ó Riaghain and Ó Maoilriaghain, which Woulfe gives alongside the shorter modern Ó Riain and Ó Maoilriain.[12][1][2]
What does the name Ryan mean?
Ryan means 'descendant of Rian', but the meaning of Rian is unknown. Sources cited by Wikipedia, including Edward MacLysaght and the historian John Ryan, say it has never been satisfactorily explained. Suggested links to Old Irish words for 'water' or 'king' have been discounted by scholars. 'Little king' is a popular modern explanation without scholarly backing.[3]
Are Mulryan and Ryan the same name?
Often, yes. Woulfe records that the Ó Maoilriain of Owney were anglicised O'Mulryan or Mulryan and then, by dropping the first part, Ryan. He uses Ryan for O'Mulryan as an example of how anglicised names were cut down. Ó Maoilriain is a different Gaelic name from Ó Riain, however, so a Mulryan and a Carlow O'Ryan are not necessarily related.[2][9][1]
Where does the Ryan name come from in Ireland?
There are two main homelands. The Ó Riain were lords of Idrone in County Carlow and spread through Leinster. The Ó Maoilriain held Owney, in north Tipperary and east Limerick, from about the 13th or 14th century, and became very numerous there. A few Ryans in Connacht, especially Mayo, carry names that were originally Ó Ruadháin or Ó Sraitheáin.[1][2][4][11]
Is there a Ryan family crest?
No single crest belongs to everyone called Ryan. In Irish and British practice, arms were granted to particular families or individuals and passed down through their own descendants. Ryan also combines at least two separate Gaelic families. The sources used here record no arms or motto for a named Ryan sept, so be wary of any 'Ryan family crest' sold for the surname as a whole.[1][2]
Where in Ireland is the Ryan surname most common?
In the 1911 census the largest numbers of Ryans lived in Tipperary (10,732), Limerick (4,596), Dublin (3,144). Relative to population, the name was most concentrated in Tipperary (703 per 10,000), Limerick (321 per 10,000), Kilkenny (192 per 10,000).
How common was the Ryan surname in Ireland?
30,675 people were recorded as Ryan or O'Ryan in the 1911 census of Ireland, making it the 8th most common surname. That is roughly 0.7% of the population, or 1 person in 143.
