Michaelston-le-Pit (Welsh: Llanfihangel-y-pwll) is a village to the west of the city of Cardiff, Wales. The community population taken at the 2011 census was 309.
To the south lies Penarth, while to the south west lies the village of Dinas Powys.
The village is built near the confluence of two small streams, which join to form the Cadoxton River. The French suffix is possibly derived from a clay pit near the southern end of the village, it having been settled on a Norman family, the De Raneghs, after the conquest.
Llanfihangel-y-pwll means The Church of St Michael and All Angels of the Pool or Pit. It is not to be confused with Latin suffixed Michaelston-super-Ely or Welsh suffixed Michaelstone y Fedw
Rev. Henry Holmes Stewart (1847–1937), who won the FA Cup with Wanderers in 1873, was rector at the parish church from 1925 to 1935.
The village is the home to former Welsh First Minister Rhodri Morgan.
