Carmarthen East and Dinefwr is a constituency of the National Assembly for Wales. It elects one Assembly Member by the first past the post method of election. Also, however, it is one of eight constituencies in the Mid and West Wales electoral region, which elects four additional members, in addition to eight constituency members, to produce a degree of proportional representation for the region as a whole.

It had been held since its formation in 1999 by the Plaid Cymru politician, Rhodri Glyn Thomas until his retirement in 2016, it is now held by Plaid Cymru politician Adam Price.

The constituency was created for the first election to the Assembly, in 1999, with the name and boundaries of the Carmarthen East and Dinefwr Westminster constituency. It was a Dyfed constituency, one of five constituencies covering, and entirely within, the preserved county of Dyfed.

The other four Dyfed constituencies were Carmarthen West and South Pembrokeshire, Ceredigion, Llanelli and Preseli Pembrokeshire. They were all within the Mid and West Wales electoral region.
