Lennon is Irish in Origin.

Lennon is an Anglicized Irish surname with twin Gaelic roots: Ó Leannáin, from leannán “lover, sweetheart,” and Ó Lonáin/Ó Lionáin, from Lonán, a diminutive of lon “blackbird.” Thus the name carries the senses “lover” and “little blackbird.” The surname appears across medieval Connacht and Ulster, later yielding forms such as Lennon and Lannon through Anglicization. Lonán features in early Irish annals as the name of saints and poets, while leannán survives in phrases like leannán sídhe, the “fairy lover,” in folklore.

As a given name, Lennon rose in the late 20th century, strongly influenced by singer-songwriter John Lennon and the modern fashion for surname names. Usage is unisex in English-speaking countries, with notable growth since the 2000s. Variant spellings include Lennan, Lennen, Lenon, and Lannon; contemporary tweaks like Lennyn also appear. Common short forms are Len, Lenny/Lennie, and Leni.
