March music festivals mark the true beginning of festival season, headlined by South by Southwest (SXSW) in Austin — one of the world's most influential music and culture events — alongside growing lineups of spring festivals across the country. March is when the festival calendar begins to fill rapidly, with events spanning country, indie rock, electronic, jazz, and folk genres in cities from New Orleans to Los Angeles.
Spring break also brings festival events to beach and resort destinations, while cities begin hosting outdoor events as temperatures warm. March is the ideal time to start locking in summer festival plans before the biggest events sell out. Browse all March 2026 music festivals below.
