HMS Hector was an armed merchant cruiser of the Royal Navy. Initially built as a passenger cargo vessel, she was requisitioned by the Admiralty during the Second World War. She was sunk in a Japanese air attack in 1942 and was later raised and scrapped.
She was drydocked in Colombo to prepare for decommissioning. Whilst in harbour with other ships, the port came under attack from Japanese carrier-based aircraft, as part of the Indian Ocean raid. Colombo was targeted on 5 April in the Easter Sunday Raid. The Japanese force, led by Admiral Chuichi Nagumo, had hoped to catch the remnants of the Eastern Fleet in harbour. However, most of the fleet had left several days earlier. Japanese aircraft found only three targets in the harbour, and so proceeded to attack them. The Hector was hit by bombs and set on fire. She was abandoned and later sank. The Japanese also sank the destroyer HMS Tenedos in the harbour, before locating and sinking the cruisers HMS Cornwall and HMS Dorsetshire out at sea. The wreck of the Hector was nominally returned to the Ocean Steamship Company on 20 April 1942, but the ongoing war meant that she was not refloated until 1946. She was then beached five miles north of Colombo for assessment. It was concluded that she was beyond economical repair, and she was sold for scrapping.
