Dr. Jill Roberts is a recurring character on the action/comedy series Chuck on NBC. She is a prominent figure in the series' mythology, though did not appear until the middle of the second season. Jill is Chuck's ex-girlfriend from Stanford, and is portrayed by Jordana Brewster. Jill has made the most recurring appearances among Fulcrum agents in the series (with four appearances), surpassing Ted Roark and Vincent, who have each made three appearances.

Most of what is known about Jill in the series has been revealed by Chuck, and prior to Sarah Walker, Jill was the love of his life. It was revealed in "Chuck Versus the Alma Mater" they met through their mutual friend Bryce Larkin (Matthew Bomer) at Stanford in 1999, and after growing closer as friends, eventually began to date. In 2003, Chuck was expelled after being framed for stealing the answer keys to tests for one of his classes by Larkin. A flashback in "Chuck Versus the Ex" shows he returned to Stanford briefly in an effort to explain the situation, but Jill told Chuck it was over between them. She also didn't contradict her roommate when the latter said Jill had begun seeing Bryce.

She graduated from Stanford with high grades, and her school performance attracted Fulcrum's attention while she was still attending school. They began exerting pressure on her, until it was too late for her to escape from their influence. According to Chris Fedak, Jill was recruited into Fulcrum by her Uncle Bernie. In "Chuck Versus the First Kill", Bernie is revealed to be her father's best friend. After Chuck was expelled through the actions of Larkin, she was ordered by Fulcrum to break off her relationship with Chuck. The best way she knew how was to tell him she had started seeing Bryce. During the course of her recruitment, she also received espionage and firearms training.

In "Chuck Versus the Ex", set six years after Chuck's expulsion, he and Jill unexpectedly reunite while he was providing technical support for a scientific conference that Jill was attending with her boss, Dr. Guy LaFleur. Chuck was ordered to use his connection with Jill to learn more about LaFleur, who was suspected of developing a biological weapon. After LaFleur was killed by a Fulcrum agent, Jill revealed that he actually uncovered the plot and was attempting to stop it. Chuck later identified himself as a government operative to obtain her assistance once the bioweapon was unleashed in a scientific conference. After this, she and Chuck began dating again in secret while Chuck continued to maintain his cover relationship with Sarah, which both women found uncomfortable as they were both jealous of each other. In "Chuck Versus the Fat Lady", Jill aided the team when they began to search for a list of Fulcrum agents that LaFleur had stolen and had intended to turn over to the CIA. As Jill was familiar with the puzzles LaFleur used to protect his valuables, she was able to assist the team with recovering the data. As Chuck and Jill decided to embark on a romantic getaway, Casey and Sarah were reviewing the list and matching it with a list of government agents. It was then revealed Jill was in fact a Fulcrum agent.
