Uzmaston is a small parish[1] in Pembrokeshire, Wales, about 1 mile (1.6 km) south-east of Haverfordwest.

[5] At the time of the 1851 census, Uzmaston belonged to a parish comprising an area of 2,070 acres with a population of 683 people, 307 male and 376 female.

Samuel Lewis, writing in his A Topographical Dictionary of Wales, stated that Uzmaston "comprises a moderate extent of enclosed and cultivated land: the soil is generally fertile, and the inhabitants are chiefly employed in agriculture.

The western part of it, containing the straggling extemity of a suburb of Haverfordwest, called Cartlett, is included within the new electoral limits of that borough.

[2] Geologically, the area is known for the yellow-grey[11] Uzmaston Beds, dated to the Silurian period,[12] which are unfossiliferous in the lower parts.
