Heydar Aliyev Palace (Azeri: Heydər Əliyev Adına Saray, also known as Baku Palace, formerly Republic Palace (Respublika Sarayı) and during the Soviet era known as Lenin Palace (Лeнин aдынa) is the main music venue of Baku, Azerbaijan, seating 2158 people. The palace was renamed after the death of Azerbaijani President Heydar Aliyev in 2003. Alish Lemberanskiy was the designer and main visioner of the palace.
The venue reopened in November 2008 after extensive renovation. It was considered as possible location for the Eurovision Song Contest 2012, but the venue was later confirmed as the Baku Crystal Hall, a brand new arena and concert facility, purpose built in 2012.
