Sarah Lisa Bartowski (f/k/a Walker) is the alias of one of the main characters of the television show Chuck on NBC. She is portrayed by Yvonne Strahovski and is one of two agents assigned by the NSA and CIA to protect Chuck Bartowski after he unwittingly downloads the secret government computer known as the Intersect into his brain. In the Season 4 finale, "Chuck Versus the Cliffhanger", Chuck and Sarah were married, dismissed from government service, and given ownership of Volkoff Industries, with which they bought the Burbank Buy More and the secret Castle base thereunder. During the final three episodes of season 5, Sarah gets her memories suppressed due to a faulty Intersect upload, the signs of recovery from which are exhibited throughout the final episode.

Very little information about Sarah's past has been revealed throughout the series. The only people outside of her family confirmed to know her real name, revealed to be "Sam", are Director Graham (now dead), Daniel Shaw, and Chuck. It is otherwise only known that she has confessed her middle name is Lisa. Chuck stated she was 28 years old before he met her father for the first time, and later Gertrude Verbanski had a dossier on her stating she was born in May 1982. Her father was a con artist she introduced to Chuck as "Jack Burton," and much of her youth was spent moving from city to city under a series of aliases as part of his ongoing schemes. She attended at least her senior year of high school—and graduated in 1998—under the alias of Jenny Burton.

As a child, Sarah was not only aware of her father's activities, but actively participated in them. One of their scams was the "Lichtenstein," in which her father would masquerade as a struggling German inventor or businessman attempting to unload an invention or other valuable commodity that never actually existed. Christmases were spent scamming the Salvation Army. "Chuck Versus the Wedding Planner" reveals that Sarah spent at least some of the ten years between 1988 and 1998 in the care of her grandmother, who did not think much of her father.
