Ante Sundaraniki! (transl. The thing about Sundar is!) is a 2022 Indian Telugu-language romantic comedy film written and directed by Vivek Athreya. Produced by Mythri Movie Makers, it stars Nani and Nazriya Nazim (in her Telugu debut). The film tells the story of Sundar and Leela, an interfaith couple who try to convince their parents about their marriage through a string of lies only to find themselves in more complicated situations.

Ante Sundaraniki! was announced in November 2020 with principal photography taking place between April 2021 and January 2022. The film was predominantly shot in Hyderabad and the United States. Ante Sundaraniki! was released in theatres on 10 June 2022 and opened to positive reviews from critics.

It grossed over $1 million overseas, making it Nani's seventh film to do so. The film grossed over ₹45 crore worldwide. Despite receiving positive reviews from critics, praising its narrative, performances, and technical aspects, the film failed to perform well at the box office. Over the years, however, it gained a loyal fanbase and is now regarded as a cult classic.
