Katha Sangama (transl. Confluence of tales) is a 1976 Indian Kannada-language anthology film, directed by Puttanna Kanagal, based on three short stories; Hangu by Giraddi Govindaraj, Athithi by Veena and Munithaayi by Eshwara Chandra. The film stars Kalyan Kumar, Rajinikanth, B. Saroja Devi and Aarathi in the lead roles. The supporting cast includes Lokanath, Vamana Rao, Shivaramaiah and Master Umesh. The film won three awards at the 1975–76 Karnataka State Film Awards, including the award for Best Actress (Aarathi).

The 1984 Tamil film Kai Kodukkum Kai was an extended version of the Munithayi segment from this movie. Rajnikanth, who played the antagonist role in the Kannada movie, played the lead role in the Tamil version. The antagonist role of the Kannada movie was also an inspiration for Rajanikanth's characterization in the 1977 Tamil movie 16 Vayathinile directed by debutant Bharathiraja who was an associate of Puttanna Kanagal.
