Beddau (English: Graves Welsh: Y Beddau) is a large former mining village (and electoral ward) situated within the South Wales Valleys  around 1.5 miles (2.4 km) from Llantrisant and 4 miles (6.4 km) from the larger town of Pontypridd in the county borough of Rhondda Cynon Taf, South Wales.

The South of the village is known as Tynant (English: House in the brook and near the former Cwm Colliery and coking works now derelict and is the area where the colliery workers largely lived. It is the more traditional part of the village and has large former council housing estates. The Northern section of the village has more private housing estates and a smaller amount of former council housing.
Beddau is also the name of an electoral ward within the Llantrisant community, bordered to the east by the Tyn-y-nant ward, which includes Tynant. The Beddau ward elects a county councillor to Rhondda Cynon Taf County Borough Council. Apart from 2008 to 2012, when the ward elected an Independent councillor, the ward has been represented by the Labour Party. Since 2012 the ward has been represented by Councillor Ricky Yeo. The county councillor for the Tyn-y-Nant ward is Labour's Clayton Willis.
A 2018 review of electoral arrangements by the Local Democracy and Boundary Commission for Wales would see Beddau and Tyn-y-nant merged to form a single county ward. The proposals would take effect from the 2022 council elections.
Beddau is also a ward for Llantrisant Community Council, electing four community councillors. Tynant forms another comunity ward, electing three councillors to the community council.
Ysgol Gynradd Gymraeg Castellau is the village's Welsh speaking primary school. As of July 2016, it is a school to 256 children. English language medium schools are Gwaunmeisgyn Primary School and Llwyncrwn Primary School, which both feed into Beddau's secondary school Bryn Celynnog Comprehensive.
Beddau is served by bus services to Llantrisant, Cardiff and Pontypridd.
A station, Beddau Halt railway station on the Llantrisant and Taff Vale Junction Railway existed until 1964 quite some way south of the village. A private railway siding from the Treferig branch of the Llantrisant and Taff Vale Junction Railway to coal workings extended to the village existed for a time. Extensive sidings and rail traffic served Cwm Colliery and coking works until 1984 when the line to junction at Pontyclun station was closed and mothballed. Efforts are being made to reopen this line to passenger traffic.
