The International Documentary Film Festival Amsterdam (IDFA) is the world's largest documentary film festival held annually since 1988 in Amsterdam. Over a period of twelve days, it has screened more than 300 films and sold more than 250,000 tickets. Visitors to the festival have increased from 65,000 in 2000 to 285,000 in 2018.

The festival is an independent, international meeting place for audiences and professionals to see a diverse (in form, content and cultural background) program of high-quality documentaries. IDFA selects creative and accessible documentaries, which offer new insights into society. 

In its mission statement, IDFA says it ‘strives to screen films with urgent social themes that reflect the spirit of the time in which they are made’.

The festival was initially held at the Leidseplein area in the centre of Amsterdam. It has since spread to a number of other locations, including Tuschinski Cinema and EYE Filmmuseum.
