The Hario (針尾) was a Japanese fleet oiler, serving during World War II. Four vessels were planned under the Maru Sen Programme; however, only one vessel was completed by the end of war.

The Hario-class oilers were planned instead of the cancelled Kazahaya class oilers. The Navy Technical Department (Kampon) armed these vessels as a Type 1TL wartime standard ship.

The Hario was completed and assigned to the Combined Fleet on 1 December 1944, joining the Hi-89 convoy from Moji to Singapore on 24 January 1945. She arrived in Singapore on 9 February 1945, joining the Hi-94 convoy (returning to Moji from Singapore) on 23 February 1945. On 1 March, she arrived at a relay point at Yulin, Hainan. Two days later, on 3 March, she left Yulin, only to hit a mine and sink the same day.^[1] She was decommissioned 10 May.
