Khiladi 420 (English: Player 420) is a 2000 Indian Bollywood action thriller film directed by Neeraj Vora and starring Akshay Kumar and Mahima Chaudhry. The film was written by Uttam Gada and released on 29 December 2000. It is the seventh installment in the Khiladi series starring Kumar, which included Khiladi (1992), Main Khiladi Tu Anari (1994), Sabse Bada Khiladi (1995), Khiladiyon Ka Khiladi (1996), Mr. and Mrs. Khiladi (1997) and International Khiladi (1999).

This film marked the third time Akshay Kumar played a dual role after Jai Kishen (1994) and Aflatoon (1997). After Aflatoon, this was the second time Kumar played both a positive and negative role.

The film is notable for featuring some of Akshay Kumar's most dangerous stunts, including a scene where he catches and climbs a running plane, stands on top of it, and then jumps onto a hot air balloon while 1,000 feet up in the air; the stunt drew comparisons to Jackie Chan. However, the film was a box office failure, and was the last Khiladi film up until Khiladi 786 (2012) twelve years later.
