The Princess of Wales Theatre is a 2,000-seat live theatre in Toronto, Ontario, Canada. It is located on King Street West, in Toronto's downtown Entertainment District. The theatre's name has a triple meaning: it honours Diana, Princess of Wales, with whose consent the theatre was named; it links the building to its sister theatre, the Royal Alexandra, one block to the east, also named – with Royal assent – for a former Princess of Wales; and it recalls the Princess Theatre, Toronto's first "first-class legitimate" playhouse, that stood three blocks to the east until 1931.

Downtown Toronto is the main central business district of Toronto, Ontario, Canada. Located entirely within the district of Old Toronto, it is approximately 16.6 square kilometres in area, bounded by Bloor Street to the northeast and Dupont Street to the northwest, Lake Ontario to the south, the Don Valley to the east, and Bathurst Street to the west. It is also the home of the municipal government of Toronto and the Government of Ontario.
