Nachikatsuura is located near the southern tip of the Kii Peninsula, in the southeastern tip of Wakayama Prefecture. It faces the Pacific Ocean to the east and its coastline is a typical ria coast with several good natural harbors. In particular, the port of Katsuura is located in a cove protected by the island of Nakanoshima at its entrance, so it is not affected by rough waves from the sea. The landscape is mountainous, with numerous hot springs. Parts of the city are within the limits of the Yoshino-Kumano National Park and are also within the Kumano area of the UNESCOWorld Heritage Site "Sacred Sites and Pilgrimage Routes in the Kii Mountain Range"

The area of the modern town of Nachikatsuura was within the ancient Kii Province. Kumano Nachi Taisha, one of the Kumano Sanzan shrines, has been a destination for pilgrims since the Heian period. The villages of Nachi and Katsuura were established with the creation of the modern municipalities system on April 1, 1889.

On April 1, 1955, Nachi and Katsura merged with the neighboring villages of Ukuimura and Wakamura to form the town of Nachikatsuura. On January 11, 1960 the municipality annexed the villages of Shimosato farther south and Otamura inland up the Ota River.
