The Sherman Theatre is a performing arts venue in the Cathays district of Cardiff. It is Cardiff's only producing theatrical venue and is home to two theatrical companies: the Sherman Theatre Company and the Sherman Youth Theatre.
Within the premises are three performance spaces: the main auditorium with 468 seats, and the arena which seats between 143 to 163. There is also a "rehearsed reading" space where events such as "Script Slam" take place on a regular basis.
Many local people see the Sherman's Christmas productions as being one of the highlights of the Christmas period.
