Gustafi are a Croatian folk rock band formed in Vodnjan, a small town in Istria, in 1980. The band was founded by Edi Maružin, Vlado Maružin, Čedomir Mošnja, Igor Arih and Livio Morosin and was originally called Gustaph y njegovi dobri duhovi. They released their first album titled V in 1985.
The band is known for their eclectic style which combines Istrian folk music and rock, along with blues and Tex-Mex influences. They are considered one of the most prominent examples of the so-called ča-val, a type of pop rock music accompanied with lyrics sung in the chakavian dialect spoken in Istria, which became popular in the mid-1990s in Croatia.
