Hazel is an American sitcom about a live-in maid named Hazel Burke (played by Shirley Booth) and her employers, the Baxters. The five-season, 154-episode series aired in prime time from September 28, 1961, to April 11, 1966, and was produced by Screen Gems. The first four seasons of Hazel aired on NBC, and the fifth and final season aired on CBS. Season 1 was broadcast in black-and-white except for one episode which was in color, and seasons 2–5 were all broadcast in color. The show was based on the single-panel comic strip of the same name by cartoonist Ted Key, which appeared in The Saturday Evening Post.

Hazel is a competent, take-charge, live-in maid in the home of the Baxter family. George Baxter (Don DeFore) is a partner in the law firm of Butterworth, Hatch, Noll and Baxter; Hazel calls him "Mr. B". George's wife, Dorothy (Whitney Blake), is an interior decorator, whom Hazel nicknames "Missy". Their son Harold (Bobby Buntrock) is dubbed "Sport" by Hazel. The family dog is Smiley. Hazel had worked previously with Dorothy's family, and has a close relationship with her.

The series humorously dramatizes Hazel's life with the Baxters and her friendships with others in the neighborhood such as postman Barney Hatfield (Robert Williams), taxi-driver Mitch Brady (Dub Taylor) and Rosie Hammaker (Maudie Prickett), another maid in the neighborhood. Many episodes focus on the perennial contest of wills between Hazel and George over issues around the house; "Mr. B" usually concedes defeat and grants Hazel's wishes when she tortures him by serving meager portions of her mouth-watering meals and desserts.

Some episodes take Hazel outside the Baxter house and follow her life in the community. In the first episode, for example, she spearheads a drive for the construction of a neighborhood playground. Hazel's life is sometimes complicated by George's snobby Bostonian sister Deirdre Thompson (Cathy Lewis) and his gruff client Harvey Griffin (Howard Smith). Dotty neighbors Herbert and Harriet Johnson (Donald Foster and Norma Varden) often call upon Hazel's expertise in household matters, of which they seem ignorant.
