Heyoke is an instrumental jazz composition in the key of F by the Canadian trumpeter and composer Kenny Wheeler, who is its sole writer. It has no lyrics. The original recording was made in June 1975 at Generation Sound in New York by Wheeler's quartet, with Keith Jarrett on piano, Dave Holland on bass and Jack DeJohnette on drums. It was released by ECM in 1976 on the album Gnu High, produced by Manfred Eicher, and marked Wheeler's first ECM session as leader. Heyoke opens side one and runs about 21 to 22 minutes, the longest piece on the album, alongside Smatter and Gnu Suite. AllMusic described the album as an auspicious but long-winded starting point, and DownBeat gave it four stars. Later recordings include versions by Jay Epstein (1997), Noël Akchoté (2015), John Law (2019) and the Antonio Zambrini trio (2023).
