Solidays (/ˈsɒlɪdeɪz/) is a French annual music festival that takes place at the Longchamp Racecourse in Paris at the end of June.

Organized by Solidarité sida (a French HIV/AIDS awareness group for youth), the event brings together more than 150 artists and 170 000 festival-goers for three days (Friday, Saturday and Sunday).

The proceeds from the festival are donated to organisations fighting against HIV/AIDS, especially for those focusing on the African continent.

The performers involved in Solidays accept a reduced fee or appear for free as a sign of their solidarity.
