Oru Vadakkan Veeragatha (transl. A Northern Ballad of Valour) is a 1989 Indian Malayalam-language epic historical drama film directed by Hariharan, written by M. T. Vasudevan Nair, and starring Mammootty, Suresh Gopi, Balan K. Nair, Captain Raju and Madhavi. The film won four National Film Awards (1989) including Best Actor (Mammootty), Best Screenplay (M. T. Vasudevan Nair), Best Production Design and Best Costume Design (P. Krishnamoorthy) and eight Kerala State Film Awards.

This film is based on a subplot of Vadakkan Pattukal, a medieval ballad from North Malabar and is often regarded as a classic of Malayalam cinema. The story is a reinterpretation of the life of the legendary Chandu Chekavar and depicts him as an unlucky and misunderstood but ultimately honourable man rather than the traitorous character that earned him the sobriquet of Chathiyan Chandu (literally 'Chandu the Betrayer') in folklore.
