Theatre NO99

The building of NO99 on Sakala street, Tallinn.

Theatre NO99 was a theatre in Tallinn, Estonia that began to operate in February 2005. It was a state-owned repertoire theatre that has its own building with two theatre halls in central Tallinn. The theatre closed in 2019.

The theatre's name was NO99, although it has no connection with classical No Theatre. NO is an abbreviation of the word “number” and 99 has decreased by one with each new production.
