This is a list of people who have served as Lord Lieutenant of Essex.
Since 1688, all the Lord Lieutenants have also been Custos Rotulorum of Essex.
Deputy lieutenants support the work of the lord-lieutenant.
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.
