Happiness is a Four-letter Word is a 2016 South African romantic drama film directed by Thabang Moleya and written by Busisiwe Ntintili. Based on the novel of the same name by Nozizwe Cynthia Jele, the film tells the story of three friends trying to find their happiness while maintaining images of success and acceptability.

The film revolves around three women. Glamorous trophy housewife Zaza, played by Khanyi Mbau, seems to be living the new South African dream of money, success, and loving partners. Lawyer and compulsive perfectionist Nandi, played by Mmabatho Montsho, whose life from the outside is perfect, has a great career and forthcoming nuptials, but in reality, she is suffocating. Trendy art gallery owner and serial dater Princess is played by Renate Stuurman. The three friends juggle life's surprising changes as they come to learn that "happiness doesn't come with a manual". The three will have to find out what truly makes each of them happy and then fight to get it in their unique way.

A sequel is currently under development, set to premiere on Netflix later this year.
