Lehane (Irish: Ó Liatháin) is an uncommon Irish surname, typically from County Cork. Ó Liatháin is more frequently anglicized as Lane or Lyons. . Most people with this surname derive from the ancient Munster kingdom of Uí Liatháin, which was powerful in the early to mid 1st millennium, and one of the few important Irish kingdoms to have colonies in Britain, documented in both Irish and Welsh sources (see Byrne 2001; Ó Corráin 2001).
