"Who Stole the Cookie from the Cookie Jar?" or the Cookie Jar Song is a sing-along song/game, sung usually with young children in a pre-school, school, or day camp setting. The song is an infinite-loop motif, each verse directly feeds into the next. It is usually performed as a fun game, with the children sitting or standing in a circle.

The song usually begins with the group leader asking who stole a cookie from an apocryphal (or, in some cases, real) cookie jar, followed by the name of one of the children in the circle. The child questions the "accusation," answered by an affirmation from the "accuser," followed by continued denial from the "accused." The accuser asks who stole the cookie, followed by the name of another child in the circle. The call-and-answer is potentially infinitely recursive, limited only by the number of participants or the amount of time the participants wish to spend on it.

Sometimes, a clapping or snapping beat is used by the children in the circle. Sometimes, the other children in the group sing along with the "accuser" after the "accused" has been identified. Some variations on the theme include the use by teachers of the song as a lesson in keeping with a beat and improvisation. As with many children's songs, there can be many variations on the execution of the performance.
