Tōno (遠野市, Tōno-shi) is a city in Iwate Prefecture, Japan. As of 1 January 2020, the city had an estimated population of 26,378, and a population density of 31.6 persons per km in 10,759 households. The total area of the city is 825.97 square kilometres (318.91 sq mi). Tōno is known as "The City of Folklore" for its rural nature, its preservation of traditional culture and especially for the collection of folktales, Tōno Monogatari, written by Kunio Yanagita in 1910.

Tōno is located in central Iwate Prefecture, in the floodplain of the Sarugaishi River, surrounded by a ring of mountains. Mount Hayachine sits at the northernmost point of the city where Hanamaki, Kawai and Tōno meet. At 1,914 meters it is also the city's highest point. Mt. Rokkoushi, (1,294 meters) dominates the landscape to the east and Mt. Ishigami (1,038 meters) is the highest mountain in the west. Together these peaks form Tōno's "big three" mountains. The highest points in southern Tōno are Mt. Sadato (884 meters) on the border of Sumida and Mt. Tane (871 meters) on the borders of Sumita and Ōshū.

Accordingly, to legend, in the past the hills in Miyamori blocked the Sarugaishi River creating a large lake in the Tōno area. Miyamori itself is characterized by a series of valleys to the west of Mt. Ishigami that flow west into the Sarugaishi River just below the Tase Dam.

The area of present-day Tōno was part of ancient Mutsu Province, and has been settled since at least the Jōmon period. Pottery fragments can still be found in farmers' fields and other places. Later the area was inhabited by the Emishi and many place names are based on the Ainu language. In the Early Nine-Years War lasting from 1051 to 1063, Minamoto no Yoshiie fought running battles with Abe no Sadato throughout the area. There are references to this in "Tōno Monogatari" and arrowheads still turn up from time to time. Later the Hiraizumi Fujiwara controlled Tōno which was a prized area for horse breeding, farming and hunting.

During the Sengoku period, the area was dominated by various samurai clans before coming under the control of the Nambu clan during the Edo period, who ruled Morioka Domain under the Tokugawa shogunate. The Nambu built Nabekura Castle in what is now known as Nabekura Park in downtown Tōno as a defence against the powerful Date clan of Sendai Domain to then south, and assigned to Nanbu Naoyoshi, formerly castellan of Ne Castle near Hachinohe in 1627. This formed an unofficial subsidiary 12,500 koku domain of Morioka Domain, which lasted until the Meiji restoration.

With the Meiji period establishment of the modern municipalities system, the town of Tōno was established on April 1, 1889 within Nishihei District of Iwate Prefecture. In 1896, Nishihei and Minamihei districts were merged to form Kamihei District. During the Meiji period, Tōno developed a silk and cotton weaving industry dependent on Morioka. The silk industry was destroyed by intensely cold weather during the winter of 1905–06. The residents of Tōno were reduced to eating wild roots by the famine of this period and many died or moved away.

The city of Tōno was officially founded on December 1, 1954 by the merger of the former town of Tōno with the seven villages of Ayaori, Otomo, Tsukimoushi, Matsuzaki, Tsuchibuchi, Aozasa and Kamigo.

On October 1, 2005, the village of Miyamori (from Kamihei District) was merged into Tōno to bring the city to its present boundaries.

Tōno has a mayor-council form of government with a directly elected mayor and a unicameral city legislature of eighteen members. Tōno contributes one seat to the Iwate Prefectural legislature. In terms of national politics, the city is part of Iwate 3rd district of the lower house of the Diet of Japan.

There are two senior high schools in Tōno, under the purview of Iwate's Prefectural Board of Education. Iwate Prefectural Tōno Senior High School offers an academic curriculum, while Iwate Prefectural Tōno Ryokuhō Senior High School is vocational.

The Tōno city board of education operates three junior high schools: Tōno, Tōno-Higashi, and Tōno-Nishi, and 11 elementary schools: Aozasa, Ayaori, Kamigō, Masuzawa, Miyamori, Otomo, Tassobe, Tōno, Tōno North, Tsuchibuchi, and Tsukimoushi.

Tōno is known throughout Japan as the cradle of Tōno Monogatari (Tales of Tōno), written in 1910 by Kunio Yanagita, who gathered folk tales of the area. This book is now considered one of the greatest studies of Japanese folklore, and inspired the 1982 movie of the same name.

Several of these tales involve the Kappa, mischievous water sprites. A legendary location in Tōno is the Kappa-buchi, a water stream where kappas are said to live.

The mascot of the city, Karin-chan, is a cute kappa holding a bellflower. She is usually depicted walking in front of a magariya.

Tōno is also twinned with three Japanese cities:

• Mitaka, Tokyo, since 1989
• Musashino, Tokyo, since 1988
• Kikuchi, Kumamoto, since 1998

From 1990 to 2010, the high schools of Tōno and the Chattanooga School for the Arts & Sciences (CSAS) in Chattanooga, Tennessee were paired by School Partners Abroad to establish an exchange program. Near the end of every Japanese school year (in March), a delegation of Tōno high-school students visited Chattanooga, and reciprocally, a delegation from CSAS visited Tōno every summer. The city of Tōno embraced this exchange and organized a delegation of junior high school students to visit CSAS and the Chattanooga School for the Liberal Arts (CSLA) a few weeks before the high school students. After many delegations between the two cities, Chattanooga and Tono became sister cities on September 15, 2017.
