FinnFest USA is an annual festival, typically held in the summer, in locations throughout the United States of America.

The inaugural festival was held in Minneapolis, Minnesota, in 1983 with approximately 1,000 people attending.

Subsequent festivals have taken place in locations throughout the country, typically hosted by communities with connections to Finnish-American cultural history.

Festival events include lectures, classes, concerts, films, theatrical performances, dances, exhibitions and ceremonies.

The festivals are financed by registration fees, event tickets, raffles, and many forms of donation and sponsorship.
