Giants of Rock was an annual hard rock and heavy metal festival in Hämeenlinna, Finland. It was held from 1987 to 1992 at Ahvenisto Race Circuit. The 1992 festival caused financial losses for organizers due to cancellations of some headlining acts. The last festival was arranged in 1994 as Power of Rock.
In 1988 Motörhead recorded their performance. It was later released as the band's second live album Nö Sleep at All.
