Ukrainian Sea Guard (; full name Морська охорона Державної прикордонної служби України, Sea Guard of the State Border Guard Service of Ukraine) is the coast guard service of Ukraine, subordinated to its Border Guard Service. Sea Guard vessels bear the Морська охорона inscription on their boards. Ukrainian Sea Guard is the local successor of the Soviet Border Troops Naval Units that have been similarly responsible for coast guard tasks. However, there were some interchanges in units, ships and personnel between Sea Guard and the Ukrainian Navy.
