Kiyoo Wadati (和達 清夫, Wadachi Kiyoo, September 8, 1902 – January 5, 1995) was an early seismologist at the Central Meteorological Observatory of Japan (now known as the Japan Meteorological Agency), researching deep (subduction zone) earthquakes.

It was Wadati's 1928 paper on shallow and deep earthquakes, comparing maximum below surface displacement against distance from the epicentre, which led Charles Richter to develop his earthquake magnitude scale in 1935.
