The Putrajaya Monorail is an incomplete monorail system in Putrajaya, Malaysia. Construction has been stalled since 2004, and while revivals have been proposed periodically, as of 2023 there are no plans to revive the project.

Putrajaya, officially the Federal Territory of Putrajaya, is the administrative centre of Malaysia. The seat of the federal government of Malaysia was moved in 1999 from Kuala Lumpur to Putrajaya because of overcrowding and congestion in Kuala Lumpur, whilst the seat of the judiciary of Malaysia was later moved to Putrajaya in 2003. Kuala Lumpur remains as Malaysia's national capital city per the constitution and is still the seat of the head of state and the national legislature, as well as being the country's commercial and financial centre.
