Cheenu Mohan (17 May 1956 – 27 December 2018) was an Indian actor who appeared in Tamil language films and plays. He acted in films including Thalapathi (1991) and Iraivi (2016).

Mohan began his career as a stage actor in the late 1970s, portraying a lead role in plays written by Crazy Mohan. His character name of 'Cheenu' in Crazy Mohan plays, became an identification mark of him since then. He portrayed small roles in Varusham Padhinaaru (1989), Mani Ratnam's Anjali (1990) and Thalapathi (1991). His involvement in theatre and his reluctance to move into television roles, meant that roles in the film industry had evaded him.

He made a comeback by portraying a supporting role in Karthik Subbaraj's multi-starrer Iraivi (2016). Featuring as the antiques dealer John, who tries to hold together a breaking family, Cheenu Mohan received critical acclaim for his work in the film. A critic called his performance "fantastic in the melodramatic scenes". Appreciation for his performance in the film meant that he was later selected to feature in Manikandan's Aandavan Kattalai (2016) and Vetrimaaran's Vada Chennai (2017); his role in the latter film was deleted.

Mohan died on 27 December 2018 due to cardiac arrest.
