*Tanya Mousekewitz is the tritagonist in the An American Tail franchise. She is the cute and lovely big sister of Fievel Mousekewitz.

The oldest Mousekewitz sibling, she loves her little brother a lot. Her singing voice is thought by others, especially Cat R. Waul, to be beautiful.

Here Tanya, still younger from the previous prequel, has a job as a secretary at the Daily Nibbler, a job Tony helped her get. She wears a professional dress and tries to act more adult, partly because of the crush she has on editor Reed Daley. She's embarrassed to have Fievel tag along with her, afraid he'll make her look less professional. Tanya's hopes are dashed when Nellie Brie and Reed get together at the end of the movie, and in the final scene where the family is at the beach, she laments that her life has no meaning. she later watches Fievel sleep beside Yasha (who is quite awake), and Tanya, Mama, Papa, Tony, & Tiger have a Group Hug.
