This is a list of people who have served as Lord Lieutenant of Pembrokeshire.
After 1715, all Lord Lieutenants were also Custos Rotulorum of Pembrokeshire.
On 31 March 1974, the post was replaced by that of Lord Lieutenant of Dyfed.
There can be several deputy lieutenants at any time, depending on the population of the county.
Their appointment does not terminate with the changing of the lord-lieutenant, but they usually retire at age 75.
