Jean Millington is Filipino American bassist, born 25 May 1949 in Manila, Philippines. She's the sister of June Millington, both once in the trendsettiing, all-girl band Fanny. She married Earl Slick in 1976 (but later divorced), and they have two children together.

In 2018, she had a stroke from which she is recovering, partly due to a Facebook fund raiser by her sister.
