Mr. Majnu (transl. Mr. Lover Boy) is a 2019 Indian Telugu language romantic comedy film written and directed by Venky Atluri, and produced by B. V. S. N. Prasad under Sri Venkateswara Cine Chitra. The film features Akhil Akkineni and Nidhhi Agerwal in lead roles. Upon release, the film received mixed reviews, with praise towards Akhil and Nidhhi's performance, and the soundtrack, but criticism towards the plot. The film became a commercial failure at the box-office.

The film had also been dubbed in Hindi and Kannada under the same title, and in Tamil as Maanidan. The film was remade in Odia with the same name, starring Babushaan Mohanty and Divyadisha Mohanty in the lead roles, which also took inspiration from the 2010 Tamil film Theeradha Vilaiyattu Pillai.
