Ellington is a swinging musical name, evoking the jazzy and elegant persona of the Duke (born Edward Kennedy Ellington). While that reference may seem to make Ellington a male name, it is also occasionally used for girls.

Ellington's popularity may be inspired by jazz great Duke, but the name is used slightly more often for girls today, perhaps because of its trendy El- beginning. Like a host of other El- names, from the familiar Ella to Eleanor to the more niche Elodie and Elula, Ellington carries the popular Ellie nickname.
