The Kedah State Legislative Assembly (Malay: Dewan Undangan Negeri Kedah) is the state legislature of the Malaysian state of Kedah. It is a unicameral institution, consisting of a total of 36 lawmakers representing single-member constituencies throughout the state.

Members of the unicameral state legislature are called state assemblymen. The Legislative Assembly building is located at the Wisma Darul Aman in the state capital, Alor Setar.

Out of the 36 seats, 33 are held by the Perikatan Nasional (PN) ruling coalition after the 2023 state election. Thus, the PN coalition commands a two-thirds supermajority in the assembly. Meanwhile, Pakatan Harapan (PH) that comprises People's Justice Party (PKR) holds just 2 seats, followed by Democratic Action Party (DAP) which retain only single seat.

The Kedah State Legislative Assembly's main function is to enact laws that apply in the state. It is also the forum for members to voice their opinions on the state government's policies and implementation of those policies. Under the law, assemblymen are given the right to freely discuss current issues such as public complaints. On financial matters, the Assembly approves supply to the government and ensures that the funds are spent as approved and in the tax-payers' interest.

The State Executive Council (EXCO) is appointed from members of the State Assembly. Led by the Menteri Besar, it exercises executive power on behalf of the Sultan and is responsible to the Assembly.
