It's a Mad, Mad, Mad World (富貴逼人) is a 1987 Hong Kong Chinese New Year film, directed by Clifton Ko. It starred Bill Tung and Lydia Sum as parents of the dysfunctional Piu family. The daughters were played by Elsie Chan, Loletta Lee and Pauline Kwan.

The comedy was very popular and the original cast of Tung, Shum, Chan, Lee and Kwan reappeared in its sequels It's a Mad, Mad, Mad World II (富貴再逼人) (1988), It's a Mad, Mad, Mad World III (富貴再三逼人) (1989) and It's a Mad, Mad, Mad World Too (富貴黃金屋) (1992). The plots of the films are all about the family becoming suddenly rich, usually through lotteries. The family also made a cameo appearance in The Banquet (1991).
