The city's name is spelled "たつの", using hiragana, but the name of Tatsuno Station uses the kanji characters "竜野", while the historic name for the place uses the characters "龍野." According to the Harima no Kuni Fudoki, the origin of the name "Tatsuno" was that upon the death of Nomi no Sukune in Ibo District (now in the city of Tatsuno), many came from Izumo and used rock from the Ibo River to make a grave, standing stones in a row on the plain. Thus, it was called "立野", with characters meaning "stand" and "plain", from which it is thought to have changed to "龍野". Nomi no Sukune Shrine is located at the place said to be his grave.

Tatsuno is located in southwestern Hyōgo Prefecture extending largely south to north. The city's northern region is mountainous, the southern region faces the Seto Inland Sea, and the Ibo River runs through from north to south.

The Tatsuno area was part of ancient Harima Province and was an important location for traffic on the Izumo Kaidō highway running along the Ibo River, and was the location of Kinoyama Castle, a stronghold of the Akamatsu clan in the Muromachi period. After Oda Nobunaga gained supremacy during the Sengoku period, the area became the territory of the Ikeda clan, who ruled Himeji Domain in the early Edo period. Following Ikeda Toshitaka's death, his lands were divided by the Tokugawa shogunate and Honda Masatomo, was installed as daimyō of the newly created Tatsuno Domain. The town prospered as a castle town and the domain passed through various rulers, ultimately coming under the rule of the Wakisaka clan beginning in 1672, lasting 200 years and 10 generations, after which came the Meiji Restoration. The castle town's area from the early modern period is extant today in what is now the "old Tatsuno-chō area,” which still contains samurai residences and white-plastered earthen storehouses, giving the city the moniker of"Little Kyoto of Harima".

The town of Tatsuno was established with the creation of the modern municipalities system on April 1, 1889. On October 1, 2005, the towns of Ibogawa, Mitsu and Shingū (all from Ibo District) were merged into Tatsuno. To reflect the new character of the city, the kanji characters in the city's name were changed from 龍野市 to たつの市.

Tatsuno has a mayor-council form of government with a directly elected mayor and a unicameral city council of 22 members. Tatsuno, together with the town of Taishi, contributes one member to the Hyogo Prefectural Assembly. In terms of national politics, the city is part of Hyōgo 12th district of the lower house of the Diet of Japan.

Tatsuno has traditionally been famous for production of sōmen and soy sauce in Japan. However, much of the city is rural, with rice farming and commercial fishing playing roles in the economy. The city is increasing becoming a bedroom community, with 25.0% of those commuting to work go to Himeji (2010 National Census).

Tatsuno has 16 public elementary schools and five public middle schools operated by the city government and two public high schools operated by the Hyōgo Prefectural Department of Education. There is also one private elementary school and one private middle school. The prefecture also operates two special education schools for the handicapped.
