The Hayabusa-class torpedo boats (Hayabusa-gata suiraitei) were a class of fifteen 1st class torpedo boats constructed for the Imperial Japanese Navy as part of the 1896 Ten Year Naval Expansion Programme. They were completed between 1900 and 1904.

All of the vessels served in the Russo-Japanese war. They were notable for their attacks on the Russian fleet on the night of 27/28 May 1905 during the Battle of Tsushima, expending many torpedoes. They were able to inflict significant damage on a number of Russian ships, that were scuttled or sunk the next day.

After serving in World War I, all fifteen vessels were decommissioned between 1919 and 1923; some were scrapped, others turned into auxiliaries. For example, Kiji was used at the Navy Torpedo School in Yokosuka from 15 December 1923 to 2 October 1926.
