The Nimrod Theatre Company, commonly known as The Nimrod, was an Australian theatre company based in Sydney. It was founded in 1970 by Australian actors John Bell, Richard Wherrett and Ken Horler, and gained a reputation for producing more "good new Australian drama" from 1970 to 1985 than any other Australian theatre company.

The company's original theatre located in Nimrod Street, Kings Cross is now home to Griffin Theatre Company. The company moved in 1974 to Belvoir Street, Surry Hills, but retained its original name. From 1981 to 1988 it also played in the Seymour Centre theatres. The company ceased operations in 1988.

Subsequently, the Surry Hills venue became known as the Belvoir Street Theatre.
