HNoMS Viking was a 1. class gunboat built for the Royal Norwegian Navy. Like the other Norwegian gunboats of her era, she carried a heavy armament on a diminutive hull. The vessel was built at the Naval Yard at Horten, and had yard number 72.

Viking was built of steel covered with a cellulose belt. She was 62 m long with a beam of 9.3 m and a normal draft of 3.96 m. She displaced 1,123 tons. Her engines produced 2,000 ihp and drove two propellers.^[2]

Viking was not armored, but had a protective deck of 1.5 in (4 cm) thickness.^[2]

Viking's main battery initially consisted of two Krupp 15 cm MRK L/40 guns. It also had four 65 mm quick-firing guns and four 37 mm guns. She had three 'carriages' to launch torpedoes.^[2]

Viking served with the Royal Norwegian Navy until stricken in 1920. Later she was used as a hospital ship by the Norwegian Red Cross.
