This is an incomplete list of people who served as Lord Lieutenant of Denbighshire in Wales.
After 1733, all Lord Lieutenants were also Custos Rotulorum of Denbighshire.
The office was abolished on 31 March 1974, being replaced by the Lord Lieutenant of Clwyd.
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.
