The area of Karatsu was part of ancient Hizen Province. In 1591, on the coast of the northern part of the city (formerly the town of Chinzei), Nagoya Castle was constructed. The following year, it became the location from which the Imjin War was launched by Toyotomi Hideyoshi. In the middle of 1593, Terazawa Hirotaka created Karatsu Domain. In 1602, replacing Nagoya Castle, Karatsu Castle was constructed in what is now the heart of Karatsu.

Yobuko was elevated to town status on August 1, 1928. Karatsu Village was incorporated into Karatsu Town on January 1, 1932, and on September 1, 1935 both Sashi and Ōchi were elevated to town status. Sashi was subsequently annexed by Karatsu on November 11, 1941. Kyūragi was elevated to town status on May 3, 1952. On November 1, 1954 Karatsu annexed Kagami, Kuri, Minato and Onizuka.

Karatsu is famous for its Karatsu Kunchi festival, which runs annually from November 2 to November 4 and is visited by approximately 500,000 visitors from all over Japan. The festival consists of 14 hikiyama (floats made of many layers of paper mache) being carried around the city's narrow streets to calls of "Enya!". Some hikiyama members say "Yoisa!". This accompaniment is one of the 100 Soundscapes of Japan. Regularly during Karatsu Kunchi, people in this town open their homes to friends and strangers to eat and drink; the primary focus is enjoying food, beer, and shochu, and having lively conversation.
