Thinkalaazhcha Nalla Divasam (transl. Monday, an Auspicious Day) is a 1985 Malayalam-language drama film, written and directed by P. Padmarajan. The film stars Mammootty, Kaviyoor Ponnamma, Karamana Janardanan Nair, and Srividya. It tells the story of a son who wants to sell his ancestral house and put his mother in an old age home.

Thinkalaazhcha Nalla Divasam won the National Film Award for Best Feature Film in Malayalam for exploring the layers of family relationship in a rural setting threatened by urban culture and explains how the imminent breakdown of the joint family is prevented by death. However, the film has also been criticized for the portrayal of the lower caste character Kunjan in a negative light for aspiring to purchase the upper caste house.
