The Akatsuki-class destroyer (暁型駆逐艦 Akatsuki-gata kuchikukan?) was a class of four destroyers of the Imperial Japanese Navy. Almost identical in appearance to the previous Fubuki class, they are regarded as a sub-class by many authors, partly because the Imperial Japanese Navy itself kept the improvements made a secret, and did not officially designate these four destroyers as a separate class.

After a number of years of operational experience with the Fubuki class, the Imperial Japanese Navy General Staff issued requirements for four additional Special Type (特型 Tokugata?) destroyers, with a maximum speed of 39 knots (72 km/h), range of 4,000 nautical miles (7,400 km) at 14 knots (26 km/h), and armed with Type 8 torpedoes. These destroyers were intended to operate with the new series of fast and powerful new cruisers also under consideration as part of a program intended to give the Imperial Japanese Navy a qualitative edge with the world's most modern ships. The new vessels were built from 1931-1933.

The Akatsuki vessels had larger boilers and a narrower fore funnel than the previous Fubukis, and internally the number of boilers was reduced from four to three due to improvements in boiler design and efficiency. Other improvements over the Fubuki class included a splinter-proof torpedo launcher-turret, which allowed the torpedo launcher tubes to be reloaded in action.
