The Hammersmith Palais de Danse, in its last years simply named Hammersmith Palais, was a dance hall and entertainment venue in Hammersmith, London, England that operated from 1919 until 2007. It was the first palais de danse to be built in Britain. In 2009, it was named by the Brecon Jazz Festival as one of twelve venues which had made the most important contributions to jazz music in the United Kingdom.

The Palais occupied a large site on the A219 at 242 Shepherd's Bush Road, London W6, near the circular system under the A4 Hammersmith flyover. The area has two London Underground stations, a bus station, and the road network at Hammersmith Broadway.

Built in 1910 on a site formerly occupied by a tram shed for London United Tramways, the Brook Green Roller Skating Rink, which may have been closed since 1915, was acquired at the end of the First World War by North American entrepreneurs Howard Booker and Frank Mitchell, to convert it into a place to host ballroom dancing and various kinds of dance bands, among which were the new jazz bands. This first incarnation of the Hammersmith Palais was the work of architect Bertie Crewe. Its Chinese-style decoration featured lacquered columns, fretwork and a pagoda roof with silk lanterns; in the centre of the expensive sprung dance floor, made of Canadian maple, was a model mountain with a replica Chinese village and a fountain; while at each end thereof, was a low-rise bandstand encased in glass, to allow two bands to play alternate numbers for the dancers. The venue, which also featured a restaurant and a café, was considered at the time to be the largest and most luxurious establishment of its kind in Europe. The Hammersmith Palais de Danse opening night took place on 28 November 1919. Nick LaRocca's Original Dixieland Jazz Band, in those days on tour from America, played regularly at the Palais from that first night until June 1920. Many of the famous jazz stars of the day would appear in concert there, including American jazz singer Adelaide Hall, who performed at the venue during the week from 27 March to 2 April 1939, accompanied by Fela Sowande and his Florida Club Orchestra.

During the Great Depression, while dance halls saw a reduction in attendance, ice skating came into fashion instead, and replaced dancing as the most popular leisure activity. The Palais site was therefore converted into an ice rink, which was opened on 30 December 1929, with the original London Lions ice hockey team using it as a base. However, the craze proved short-lived, and by late 1934 the rink had reverted to being a dance hall. A new maple dance floor at a cost of £5,000 was installed in the venue.

In 1959, Joe Loss and his Orchestra, with singers Rose Brennan, Ross MacManus and Larry Gretton, became the resident dance band at the Palais. For the next decade, they were a regular feature every night, except on Monday's "Record Night" when only recorded music was played and no alcohol was served from the bar. The stage and rehearsal room were within earshot of the Chief Superintendent's office in Hammersmith Police Station, leading one of its occupants to observe "where else can visitors to a police station be soothed by the sound of famous dance bands?". In 1960, the Mecca organisation acquired the Palais. Other house bands during the 1960s and 1970s included Andy Ross, Ken Mackintosh, Tony Evans, and Zodiac. On many Saturday nights, in excess of 2,000 people would visit the venue. One of the features was a huge revolving stage with a band on each side (this also caused a number of accidents when microphones and stands were left on the revolve).

The Hammersmith Palais remained a popular dance venue from its start to the late 1980s, from then on hosting mainly live music gigs, but also dance nights and private events. The venue accommodated the popular School-Disco club night with its resident band, On-On, which subsequently moved to the London Forum in Kentish Town. Promoters Onyx Promotions championed Brit-Asian bands and DJs, including DCS, Heera, Juggy D, Panjabi Hit Squad, Premi, RDB, Rishi Rich and Xzecutive/San-j Sanj. The Students' Union at Imperial College School of Medicine frequently hired the Palais as a venue for student nights.

The Palais played host to countless artists; among them Bill Haley & His Comets (1974), the Beatles, the Rolling Stones, The Who, David Bowie, the Sex Pistols, Elvis Costello and the Attractions, the Cure, U2, the Jesus and Mary Chain, the Fall, Robert Plant & the Strange Sensation, Hanoi Rocks, Big Bang and Kylie Minogue and the Police. "There was the night [in 1979] when we drove in an armoured military vehicle from our show at the Hammersmith Odeon to another the same night at the Hammersmith Palais," recalled Police drummer Stewart Copeland, "while the people from both concerts were all on the street."

Bands such as PiL, the Cramps and Soft Cell, who played their "farewell" concerts there in January 1984, made the venue popular for London gig-goers.
