The Carcosa Seri Negara is a residence located on two adjacent hills inside the Perdana Botanical Gardens, Kuala Lumpur, Malaysia. Originally built as the official residence and guest house of the British High Commissioner in Malaya, it is now owned by the Government of Malaysia. The name is a composite of the two colonial mansions located on the compound: the residence, named Carcosa (completed in 1898), and the guest house, now named Seri Negara (1913).
The buildings figured prominently in the Malaysian independence movement, with several meetings held there. Since Independence in 1957, it has been used as residences for visiting dignitaries (1957–1989), and as a luxury hotel (1989–2015). Since 2017, it has been used as a museum.
