The Legislative Assembly for the Territory of Swan, commonly referred to as the Legislative Assembly or simply as the Assembly within the Territory, is the unicameral legislature of the Territory of Swan.

Each of the Territory of Swan's five districts returns five members to the Assembly. Under the Articles of Governance, the Speaker serves as the presiding officer of the legislature. Each MLA serves for a period of four years, and elections are synchronised to coincide with federal elections.

The Legislative Assembly was established in 1960 following Congress' passage of a series of four acts, including the Territory of Swan Self-Government Act. Prior to the enactment of this legislation, the Territory was, as provided by the Constitution, under the administration of Congress. Until the Legislative Assembly's establishment, a House of Assembly existed that served a purely advisory role, while Congress remained the actual legislative authority.

The current Legislative Assembly, the 15th, was convened following the 2020 general election, after which the Cygnian Labour Party was able to form government for the sixth consecutive time with the support of the Greens, who achieved an unprecedented level of representation in the Assembly and retained the balance of power. The next election is scheduled to take place on 19 October 2024.
