Yonggary (Korean: 용가리; RR: Yonggari) is a 1999 English-language South Korean monster film directed by Shim Hyung-rae (credited onscreen also as Hyung Rae Shim) and is a reimagining of the character Yonggary, originating from the 1967 film Yongary, Monster from the Deep. Despite being a South Korean production, the film's principal cast consists of Western actors such as Harrison Young, Donna Phillipson, Richard B. Livingston, Briant Wells, Brad Sergi, Dan Cashman, and Bruce Cornwell.

Yonggary was released in South Korea on July 17, 1999. An alternative cut was later released with an altered plot, new footage, and updated special effects on January 20, 2001 as Yonggary: 2001 Upgrade Edition, which was distributed in North America as Reptilian. The film was considered the most expensive South Korean film produced at the time of its release.
