The Teatro Olimpico ("Olympic Theatre") is a theatre in Vicenza, northern Italy, constructed in 1580–1585. It was the final design by the Italian Renaissance architect Andrea Palladio and was not completed until after his death. The trompe-l'œil onstage scenery, designed by Vincenzo Scamozzi to give the appearance of long streets receding to a distant horizon, was installed in 1585 for the first performance held in the theatre, and is the oldest surviving stage set still in existence. The full Roman-style scaenae frons back screen across the stage is made from wood and stucco imitating marble. It was the home of the Accademia Olimpica, which was founded there in 1555.

The Teatro Olimpico is, along with the Teatro all'antica in Sabbioneta and the Teatro Farnese in Parma, one of only three Renaissance theatres remaining in existence. Both these theatres were based, in large measure, on the Teatro Olimpico. It is still used several times a year.

Since 1994 the Teatro Olimpico, together with other Palladian buildings in and around Vicenza, has been part of the UNESCO World Heritage Site "City of Vicenza and the Palladian Villas of the Veneto".
