"Sealed with a Kiss" is the title of a song written by Peter Udell and Gary Geld. It was first recorded in 1960 by The Four Voices. While their version was released as a single, it failed to make a significant impact. In 1962, Brian Hyland, a frequent recorder of Udell's and Geld's material, released the song as a single. It became very popular, charting as high as # 3 on both the Billboard Hot 100 and the UK Singles Chart. It charted in the UK at # 7 when re-released in 1975.

The song became a hit again in 1968 when Gary Lewis and the Playboys released it as a single. This version also had a high placing on the Hot 100.

A third Top 40 Hot 100 version came in 1972, when Bobby Vinton released his version as a single. This version also placed high on Billboard's adult contemporary chart.

In 1989, Jason Donovan topped the UK Singles Chart for two weeks with his version, which featured on his debut album Ten Good Reasons. Donovan's version was a departure from the aforementioned three in that it featured elements of dance music.
