Telstar is a professional football club based in Velsen-IJmuiden. The club was founded on July 17, 1963 when the rivals VSV from IJmuiden and Stormvogels from IJmuiden decided to merge their professional divisions and continue as amateur clubs. The new club was named Telstar, after the then newly launched communication satellite. Telstar lived up to its name through a partnership, by being AFC Ajax’s satellite club for a number of seasons from the 1985/86 season onwards.

Telstar plays its home games at sports park Schoonenberg. From 2021, BUKO will be the namesake of the stadium. Since its foundation in 1963, the football club has used the song Telstar by The Tornados as the starting tune at the home games.
