At least two ships of the Royal Danish Navy have been named Herluf Trolle:
HDMS Niels Juel (F354) was a Niels Juel-class corvette in the Royal Danish Navy which was in use until 1990. The ship was named after Niels Juel, a 16th-century Danish admiral.
HDMS Peter Tordenskiold (F356) was a Niels Juel-class corvette in the Royal Danish Navy which was in use until 1990. The ship is named after Peter Tordenskjold, a 17th-century Dano-Norwegian vice admiral.
HDMS Olfert Fischer was the second member of the Herluf Trolle class of coastal defense ships built for the Royal Danish Navy. The Herluf Trolle class was built in response to a naval construction program in neighboring Imperial Germany. The Danish ships were built in the late 1890s and early 1900s. They were armed with a main battery of two 240 mm (9.4 in) guns and were capable of a top speed of 15.5 knots. Because she was intended to operate as part of a solely defensive naval strategy, Olfert Fischer had a fairly uneventful career. She visited Britain in 1911 to represent Denmark at the coronation of George V and Mary. During World War I, Denmark remained neutral and Olfert Fischer was assigned to the defense forces that guarded Danish territorial waters. Sharply reduced naval budgets in the 1920s and 1930s curtailed further activities, and Olfert Fischer saw little activity during this period, apart from testing a reconnaissance aircraft in 1922. She was eventually converted into a target ship and used for tests of aerial bombing of a ship underway in October 1936, before being sold for scrap immediately thereafter.
