The Toronto Entertainment District is an area in downtown Toronto, Ontario, Canada. It is concentrated around King Street West between University Avenue and Spadina Avenue. It is home to theatres and performing arts centres, the Toronto Blue Jays, and an array of cultural and family attractions.

The area was also home to most of the nightclubs in downtown Toronto but have mostly moved to King St west of Spadina Av just beside the Entertainment District.

The Toronto Entertainment District is represented by Ward 10 Spadina—Fort York along with the federal and provincial ridings of Spadina—Fort York and the postal codes are M5H, M5V and M5X. It is patrolled by the 52 Division of the Toronto Police Service.

In the first half of the 20th century, the original name of the neighbourhood was the Garment District and it was almost wholly industrial. The Canadian National Railway controlled a huge amount of land along the Lake Ontario waterfront, and to the north many firms took advantage of the easy access to rail and the harbour. The most important industry was textiles and fashion, and the area had few residents. Much of the area was built after the 1904 fire, which forced many businesses to move west of the Bay Street and Front area.

Among the industry, the area was home to the Royal Alexandra Theatre whose construction and launch were financed by four Toronto business leaders—Cawthra Mulock, Robert Alexander Smith, Stephen Haas, and Lol Solman. Opened in 1907, the Beaux-Arts styled proscenium-stage theatre is the oldest continuously operating legitimate theatre in North America. Following the death of the last individual from its original ownership group, the theatre began to be run by the trustees of the Cawthra Mulock estate (another one of the original owners). By then, the neighbourhood had almost fully transformed into an industrial district with additional manufacturing facilities appearing throughout. Structures such as the Gelber Building (built in 1912 by Jewish immigrants from the town of Berezhany within the Austro-Hungarian Empire's poorest province of Galicia, Louis and Moses Gelber, to house their Gelber Bros Limited wool garment manufacturing business before adding a warehouse next door in 1932) and ACME Carbon and Ribbon building (built in the 1930s for the World War I veteran James Alexander Campbell's printing and publishing business), located on adjacent corners of the intersection of Richmond West and Duncan, were among the many examples of the manufacturing industry taking over the area.

By the mid-1950s, Royal Alex turned into a money-losing operation, and was in 1962 sold for $200,000 to the forty-eight-year-old businessman Ed Mirvish, owner of the Honest Ed's discount department store. Initially unsure about what he wanted to do with the newly-acquired property—and facing the drawback of being in an increasingly neglected industrial area of town, across the street from the CP Rail Yards—the businessman eventually decided to invest in an extensive renovation of the theatre.

Hoping to attract more people to the area, Mirvish also decided to add dining to the theatrical offering. To that end, he proceeded to purchase the industrial warehouses adjacent to Royal Alex on King St. West's north side—including the 1904-erected six-storey warehouse known as the Reid Building at 266 King Street West, immediately west of the theatre—and, in 1963, open Ed's Warehouse, a prix fixe-menu restaurant. Originally meant to recreate the atmosphere of Boston's Durgin-Park—a restaurant Mirvish reportedly enjoyed—with communal seating at long tables and sawdust floors, Mirvish ultimately decided to go in a different direction with Ed's Warehouse, loading it with cheap eccentric decor. Offering simple food and Barnum & Bailey-like ambience amid garishly set interior featuring oversized oriental vases, red-flocked wallpaper, Tiffany lamps, bronze and marble statues, stained-glass windows, and lamps with naked women on their bases, the restaurant acted as a complementary offering to the theatre in hopes of increasing revenues for Mirvish via catering to patrons who may want to have dinner before taking in the show next door. Looking to reduce costs, Ed's Warehouse served a very basic pre-set menu revolving around beef (prime rib or roast), mashed potatoes, Yorkshire pudding, and gravy followed by spumoni ice cream for dessert while requiring its male patrons to wear a suit jacket and tie and insisting on it long after other dining establishments had eliminated the tradition. Nevertheless, despite its lack of culinary ambition, the establishment would go on to become one of the most famous restaurants in Toronto, running for 37 years—serving its last meal in late 1999 and closing in 2000.

The business synergy and integration between Royal Alex Theatre and Ed's Warehouse was prominently displayed, such that Royal Alex subscribers would receive their show tickets in the mail along with two complimentary coupons for Ed's Warehouse. From the mid-1970s, the popularity of Ed's Warehouse prompted Mirvish into launching numerous spinoff hospitality ventures within the warehouses around the Royal Alex Theatre, such as restaurants Ed's Seafood, Ed's Italian, Ed's Chinese, and Old Ed's, as well as Ed's Folly lounge.
