Circus Queen (1959) is a Hindi-language action drama film directed by Noshir Engineer and produced by Homi Wadia under Basant Pictures. This vintage classic stars the legendary Fearless Nadia in one of her final leading roles, playing Usha Devi, a bold and adventurous circus performer famously known as the "Circus Queen." Alongside her, the cast includes John Cawas, Sheila Kashmiri, Habib, and Shyam Kumar. The story revolves around Usha Devi's thrilling life in the circus and her equally dramatic personal life, as she is married to a police inspector named Raj Kumar. The plot follows her involvement in a crime-fighting mission filled with stunts, action, romance, and suspense—elements typical of 1950s Bollywood films.

The film's music, composed by Chitragupt with lyrics by Majrooh Sultanpuri, features memorable tracks such as "O Dilwale Nigahen Mila Le" by Mubarak Begum and "Hum Tumse Poochhte Hain Sach Sach Hamen Bataana", a duet by Mohammed Rafi and Geeta Dutt. The songs enhance the emotional and dramatic beats of the narrative, making it a full-fledged entertainer.
