"Jealousy" is a song by British Rock band Queen which has been originally released on their seventh studio album Jazz in 1978, and one year later has been released as the fourth and last single from the album. It was written by Freddie Mercury. It is known as one of the most underrated Queen songs.

The song has been released as a single only in six countries US, Canada, Brazil, New Zealand, and USSR, but failed to chart anywhere. The single was the first and last single of the band in the USSR. In the USSR B-side of the single was "Don't Stop Me Now" but in other countries the B-side was "Fun It". In 1980 the song had been included to the list of songs for the 1980 Summer Olympics which were celebrated in Moscow.

"Jealousy" was penned by Mercury and features May playing his Hairfred acoustic guitar placing small pieces of piano wire under the frets to produce the "buzzing" effect of a sitar. This effect had already been used on "White Queen (As It Began)", from Queen II. All vocals were recorded by Mercury.
