Various acts are (or were) called The Heatwave, including a Dutch sixties freakbeat band.

The Heatwave was a sixties freakbeat band from Dordrecht, The Netherlands, who were never given an official record release in the 1960s, but were embraced by mod/beat/psych fans around the globe when Grey Past Recordings released 23 of their re-emerged studio recordings and 4-track demos (1967-1969) on LP (2006) and later a limited issue CD (2010) entitled Honeymelon Teapot. After The Heatwave's demise, band members appeared in more succesful Dordrecht sixties beat outfits such as The Zipps and Inca Bullet Joe.
