The Triple Door, Music venue in Seattle, United States.

The Triple Door is a 250-seat dinner theater, lounge and music venue at 216 Union Street in Seattle, opened in fall 2003 inside the Mann building, the former home of the Embassy Theatre. Its mainstage theater seats 250, and the lounge, called the Musicquarium, hosts smaller shows alongside food and drink service.

The Triple Door occupies the Mann building at 216 Union Street, which opened in 1925 as the Embassy Theatre, an A-list movie house until the 1950s. In 1984 the extremist group The Order set off a pipe bomb there as a diversion for an armored-car robbery at Northgate Mall, and the theatre closed that year. Rick and Ann Yoder bought the building in 1999 and began renovations in autumn 2002; the venue opened in September 2003 with Skerik's Syncpated Taint Septet, whose live album from that show came out seven years later.

The lounge is called the Musicquarium, and the venue has hosted acts there such as Ottmar Liebert, Natacha Atlas, Bassekou Kouyate, The Unthanks, Greg Dulli, Edwin McCain and El Vez. Its fundraisers for children's organizations, including one auction that raised about 1.15 million dollars, are part of how the venue is known locally.
