Jillian Marie "Jill" O'Riley-Andersen is a character from the 2015 Walt Disney Pictures/Pixar Animation Studio movie Inside Out. She is the wife of Bill Andersen and the mother of Riley Andersen.
She is voiced by Diane Lane.
In Japanese dub from the movie she is voiced by Atsuko Tanaka best known voicing Motoko Kusanagi in Ghost in the Shell, Trish in Devil May Cry, Konan in Naruto, Lisa Lisa in JoJo’s Bizarre Adventure, Bayonetta in Bayonetta, and Hova in The Ant Bully.
She is very kind and motherly to Riley, and she helps her family get through tough times, like the big move. She is very understanding. There are times when she isn't patient with her husband because of his oblivious personality (she thinks she shouldn't have turned down her chance to marry a handsome Brazillian copter pilot) but she still loves him.
She also loves Riley and does her best to understand Riley, especially as their move negatively affects Riley's personality. Since Sadness seems to be the leader of her emotions (but is not a weeping mess like Riley's Sadness), it is possible this is where her understanding and compassionate nature comes from as sadness represents the ability to empathize with others or that she might've had a rough past.
