This article lists dormant baronetcies in the baronetages of England, Nova Scotia, Ireland, Great Britain and the United Kingdom. According to the Standing Council of the Baronetage, there were 177 dormant baronetcies as of 2026.

A baronetcy is classified as 'vacant' if the most recently recognised baronet has died within the preceding five years and a potential heir may be in the process of filing a formal claim to the title. After five years, if any potential heirs have failed to file a formal claim or have been unable to successfully claim the title, the baronetcy is considered 'dormant' and no longer extant, but can be re-activated should any subsequent claimant file a successful claim.

List The below table also includes baronetcies which per a study by Stephen Kershaw either have no potential heirs or are potentially extinct, but remain listed as dormant on the Official Roll of the Baronetage.
