Bullhead (Dutch: Rundskop) is a 2011 Belgian crime film written and directed by Michaël R. Roskam and starring Matthias Schoenaerts. The film is about the prohibited use of growth hormones on cattle by farmers with ties to organised crime "hormone mafia", and tells the story of Jacky Vanmarsenille, a young Limburgish farmer, who is approached by his veterinarian to make a deal with a West-Flemish beef trader. But the murder of a federal policeman, and an unexpected confrontation with a mysterious secret from Jacky's past, set in motion a chain of events with far-reaching consequences.

The film was nominated for an Academy Award in the category of Best Foreign Language Film in 2012, but lost to A Separation. The film was shot mainly in Truiens, a Limburgish dialect.
