Neodani Fault (根尾谷断層, Neodani Dansō) is a left lateral slip fault in central Japan, Gifu Prefecture, which ruptured causing the 1891 Mino–Owari earthquake (otherwise known as the Nōbi earthquake) in 1891. It caused a 6m vertical offset and 8m left lateral offset, and ruptured over 80 km. The quake was the largest ever recorded in inland Japan.
