Collyns is a modern spelling of Collins, an Irish and English surname that comes either from Ó Coileáin, "young hound", or from the medieval pet name Colin, a form of Nicholas. Collins was adopted as a girls' name in the 2010s on the model of Sloane and Emerson, and the y spelling adds a feminine touch. Collyns has moved up from around number 4000 in 2019 to number 1930 in 2025, its best rank yet.
