Jennifer "Jenny" Hart is the mother of Violet Hart and the daughter of Betty Hart. Jenny is the main protagonist in the series.
Trying to make ends meet, Jenny struggles to work multiple jobs and has trouble paying the bills. She cares for her daughter Violet and wants her to be successful. She is voiced by Kristen Wiig.
Jenny is a reasonable, modest woman who tries to see the logical answer to a situation. She is a loving mother to Violet, and a caring girlfriend to Wayne. However, she can clash with her mother when she does something absurd.
Unfortunately, she does have moments of self-doubt and suffers from stress sometimes. Whenever Jenny is in a dilemma, she turns to Jesus Christ (literally, an imaginative coping mechanism for her). Nevertheless, she always tries to find a way out of predicaments, albeit not always successful.
Jenny can also be selfish, such as playing both sides of the protests against the town's statue of Morris Culpepper to get extra tips or abandoning Brenda for a more popular group. Jenny also suffers from a fear of commitment, having ran out on her wedding with Don Reynolds and refusing to move in with Wayne, despite having been together for a couple of years. Despite that, she still a good-natured person who knows when to do the right thing.
