Meaning and origin of Lennon
Lennon is often said to mean “from an Irish surname”; the origin is uncertain, though it is usually linked to Irish roots.
Lennon comes from the Irish surname Ó Leannáin, meaning descendant of Leannán. The meaning of Leannán is often given as lover or sweetheart, but the connection is not certain, and other derivations have been suggested. The surname is known worldwide through John Lennon of the Beatles, and much of the name's modern appeal comes from that musical association. In the United States Lennon is now used for both boys and girls, with a creative, laid-back feel. It fits naturally with other musical surname picks like Hendrix and Marley. Len is a possible nickname.
Other spellings with the same sound: Lenin, Lenon.
