马来联邦（1895年－1946年；英语：Federated Malay States，马来语：Negeri-negeri Melayu Bersekutu，华语俗称「四州府」），是大英帝国在马来半岛的殖民政体之一，由半岛上4个接受英国保护的马来王朝所组成，包括雪兰莪、森美兰、霹雳和彭亨，首府为吉隆坡。

自《邦咯条约》开始，四州逐步为大英帝国所控制，其外交和防务均由英国负责。在内政方面，，除了涉及马来习俗和伊斯兰教的事务以外，四州均须聆听英国派出的参政司的意见。

1946年4月1日，马来联邦与马来属邦、海峡殖民地（不含新加坡）在英国政府管理下，组成马来亚联邦（Malayan Union）。

The Federated Malay States (FMS) was a federation of four protected states in the Malay Peninsula—Selangor, Perak, Negeri Sembilan and Pahang—established by the British government in 1895, which lasted until 1946, when they, together with two of the former Straits Settlements (Malacca and Penang) and the Unfederated Malay States, formed the Malayan Union. Two years later, the Union became the Federation of Malaya and finally Malaysia in 1963 with the inclusion of Sabah (then North Borneo), Sarawak and Singapore.
