Operation Jackpot Nalli C.I.D 999 is a 1969 Indian Kannada-language spy thriller film directed and produced by Dorai–Bhagavan. It stars Rajkumar, Narasimharaju and Rekha.

The film is the third in the CID 999 franchise, created along the lines of the James Bond and James Bond-styled films, with the first two being Jedara Bale & Goa Dalli CID 999. The success of this movie led to one more sequel - Operation Diamond Racket. This was the debut movie of actress Rekha in a lead role.

With the release of this movie, CID 999 became the first character based trilogy movie in India. This movie was praised for its angled lighting, clever use of shadows and well thought out decor such as the atmospheric arches in the lair - all of which added an element of noir to the movie. This is the longest title for a film starring Rajkumar when his movie names are written in Kannada. The movie did not have a male playback singer.
