The Nissay Theatre (日生劇場, Nissei Gekijō) is a theatre in Chiyoda, Tokyo, Japan. It is located in the Nissay Hibiya Building, designed by the architect Togo Murano. It was completed in 1963 and opened with the Japanese premiere of Beethoven's opera Fidelio by the Deutsche Oper Berlin. Since then, a wide variety of performing arts have been staged at the theatre, including kabuki, operas, musicals, and family programs.

Inside the 1,330-seat theatre, the walls and ceilings are curved and there are no straight lines. The ceiling is decorated with 20,000 pearl oyster shells.

For many years, until the company acquired its first permanent theater, it staged numerous productions by the Shiki Theatre Company.
