The Boishakhi Mela is a Bengali celebration (mela) which takes place outside of Bangladesh. It is celebrated by the Bangladeshi diaspora in the United Kingdom, United States, Canada as well as many other countries with significant Bangladeshi populations.

Mela is a Sanskrit word meaning "gathering" or "to meet" or a "fair". It is used in the Indian subcontinent for all sizes of gatherings and can be religious, commercial, cultural or sport-related. In rural traditions melas or village fairs were of great importance. This led to their export around the world by South Asian diaspora communities wishing to bring something of that tradition to their new countries.
