Richard Ng Man Tat ( ; ; born January 2, 1952) is a veteran actor in the Hong Kong film industry, with dozens of titles under his belt.

Ng has worked with famous actor and director Stephen Chow in a series of "mo lei tau" movies ("mo lei tau" translates to "brainless"/"senseless or random," and it is a genre of slapstick comedy unique to Hong Kong). Ng co-starting with Stephen Chow in a Hong Kong TVB television series called Dun Fei Final Combat (蓋世豪俠) (1989), and also the popular 1990 film All for the Winner, where he played the role of Chow's uncle. From then on, the two would grow to star in many more "mo lei tau" films in the same style as All for the Winner.

Although Ng Man Tat owes much of his popularity from co-starring with Chow in "mo lei tau" films, he has shown to be a versatile enough actor to successfully portray various different roles. A perfect example of his talent is in his portrayal of Sister 13's father in Portland Street Blues, where he played a man who could not feel anything but abuse and rejection. This role proved to be the perfect complement to his usual "mo lei tau" style with Stephen Chow. He also played Andy Lau's sidekick in the Lee Rock series in a more serious role.

In Hong Kong, Ng Man Tat is often known as "Uncle Tat," a nickname most likely influenced from his roles as Stephen Chow's sidekick (often as his uncle) in their films. Ng is sometimes credited as Richard Ng. Even though he is Stephen Chow's good friend, he stopped starring in his movies because he didn't want to be known as "Stephen Chow's Sidekick."

A native of Fujian province, Ng Man Tat was a graduate of the class of 1974's TVB Television training program where he quickly showed his chops thereafter acting in the Hong Kong television variety show 'Enjoy Yourself Tonight' and onto long running serials in 'Chor Lau Heung' and 'Police Cadet 84'. It wasn't until 1990 that he elevated his stature on the big screen pairing his complementary comedic timing as sidekick to Stephen Chow in the Cantonese dialect HK blockbuster 'All for the Winner'.
