This is a list of deputy lieutenants of Wiltshire, England.
Unlike the appointment of High Sheriff, which is for one year, the term of office of a Deputy Lieutenant normally lasts until they reach the age of 75.
The Wiltshire Lieutenancy has an establishment of up to 36 deputy lieutenants. They are chosen to reflect a wide range of interests and backgrounds, and can be appointed at any age but tend to be aged over 60; they are normally expected to serve for at least five years before they must retire on reaching the age of 75. Deputy lieutenants can be appointed for a set period of time, but this approach has never been adopted in Wiltshire.
New deputy lieutenants are nominated by the Lord Lieutenant and follow a formal process to confirm their appointment. The Lord-Lieutenant is not obliged to appoint a new Deputy Lieutenant immediately after a current Deputy Lieutenant retires and thus may hold several vacancies.
Retired deputy lieutenants can continue to use the post-nominal letters 'DL' after the date of their retirement.
