Just for Laughs (French: Juste pour rire) is a comedy festival held each July in Montreal, Quebec, founded in 1983. It is the largest international comedy festival in the world.

Just for Laughs was founded in 1983 by Gilbert Rozon as a two-day Francophone event. In 1985, Andy Nulman joined the festival's staff and introduced Anglophone events as well; under Nulman's stewardship, the festival increased to a full month, with French-speaking performers during the first half, and English speakers in the second half. International and non-verbal acts (acrobats, pantomimes, etc.) are scattered throughout the program. In 1999, Nulman left the Festival’s full-time employ; however, he directed its major Gala Shows at the St. Denis Theatre every July, and remained on the Board of Directors of the Festival's parent company. After an 11 year absence, Andy Nulman returned to Just for Laughs in July 2010 as President of Festivals and Television.

Each day, street performers, "New Vaudevillians" and other acts both vocal and visual perform throughout the city, particularly in the "Latin Quarter" -- an area known for its theatres, cafés and boutique shopping. In the evenings, the nightclubs and live venue theatres offer special programs supporting the performers. Although Just for Laughs attracts spectators from around the world, many of those in the audience are talent scouts, booking agents, producers and managers from the entertainment industry. Performing at the festival is one of the biggest opportunities for undiscovered talent to showcase their act in front of industry professionals.
