The Frogman Corps (Danish: Frømandskorpset) is the maritime special operations force of the Danish Armed Forces. On 1 July 2015, the Frogman Corps transferred from the Royal Danish Navy to the newly established Special Operations Command.

The Frogman Corps was established on 17 June 1957 based on the model of the United Kingdom's Special Boat Service, US Underwater Demolition Team, and Marinejegerkommandoen in Norway. Initially it was under the Danish Navy's Diving School at Flådestation Holmen (Naval Station Holmen, Copenhagen), but in 1972 it was made an independent unit, operationally under the submarine squadron.

The Frogman Corps' primary role is reconnaissance, but it is also tasked with assaulting enemy ships, sabotage of fixed installations, advance force and maritime anti-terrorism tasks.

It also performs special operations work on land, including anti-terrorism and anti-criminal work. The Frogman Corps support the police with matters that demand highly specialised diving. Local authorities, etc. can also benefit from the frogmen's skills, for example when underwater installations must be inspected.

The Frogman Corps trains at the Torpedo Station at Kongsøre and works through a long series of courses, e.g.:

The basic Frogman Course is nine months. Each year 500–600 applicants start the course and less than a dozen complete all nine months. Since its creation in 1957, 311 have completed the training and become frogmen as of 2015^[update].

King Frederik X of Denmark passed selection and completed continuation training to become a badged Frogman, in the course of which he earned the nickname "Pingo", when his drysuit filled with water and he was forced to waddle like a penguin.

In 2015, a DR-produced documentary detailing the life of Frogman cadets was released.
