The Manjung District, formerly known as Dindings (its official name until 1973), is a district in the south-western part of the state of Perak, Malaysia. It is the 26th-most populated district in Malaysia. It is administered by the Manjung Municipal Council (Malay: Majlis Perbandaran Manjung), which was formerly known as the Manjung District Council (Malay: Majlis Daerah Manjung) from 1 January 1980 until 31 July 2001. Seri Manjung is the district's principal urban centre while other towns include Lumut town, Sitiawan town, Ayer Tawar, Pantai Remis, Changkat Keruning and Beruas.

The district is well known for Pangkor Island, a major attraction in Perak, and also serves as the headquarters of the Royal Malaysian Navy (TLDM) at the Lumut Naval Base and dockyard. Historically, Dindings was briefly part of the British Straits Settlements colony but was returned to Perak in 1935.
