The Invincible Dragon (Chinese: 九龍不敗) is a 2019 Hong Kong crime action film directed and co-written by Fruit Chan, and stars Max Zhang, Anderson Silva, Kevin Cheng, Annie Liu, and Stephy Tang. The film follows a dragon-believing police detective (Zhang) investigating a serial murderer targeting policewomen which results in the death of his fiancée (Tang), as he hopes to enlist the dragon's help along the way.

The screenplay was conceived prior to Chan's 2014 film The Midnight After, with Pegasus Entertainment announced as the production company in 2016. Filming began in Hong Kong that year and subsequently moved to Macau, wrapping in February 2017. Post-production spanned around three years due to the extensive visual effects.

The film was theatrically released on 20 June 2019 in Hong Kong. It received negative reviews, with critics criticizing the plot, characters, themes, action sequences, and special effects, some describing it as the weakest entry in Fruit Chan's filmography.
