"Conjunction Junction" is a song written by Bob Dorough as part of the Schoolhouse Rock! series of educational songs and videos. It aired on November 17, 1973, with vocals from the celebrated jazz artist Jack Sheldon, who also appears in I'm Just a Bill. It is "by far the most recognized Schoolhouse Rock tune" according to Bob Newall and Yohe.

The frequent refrain of the song is "Conjunction Junction, what's your function? Hookin' up words and phrases and clauses." Conjunction Junction was one of seven Grammar Rock episodes, which made up the second season of Schoolhouse Rock!. To teach conjunctions and their purpose of joining clauses with and, but, or, and nor, the song uses the metaphor of a railway junction connecting railroad cars.
