The Yilan Plain in which the city is located has historically been referred to as Kapalan (Chinese: 蛤仔難; Pe̍h-ōe-jī: Kap-á-lān), Kapsulan (蛤仔蘭; Kap-chú-lân; also 甲子蘭), Komalan (噶瑪蘭; Kat-má-lán), etc. These names, as well as that of Yilan itself, were given to the sites by the Kavalan tribe of Taiwanese aborigines. Later arrivals included Han Chinese settlers during the Qing Dynasty in China (1802) and settlers from Okinawa during Taiwan's Japanese era (1895-1945).
In 1810 under Qing dynasty rule, a formal administration office was established at Wuwei (五圍) and "Komalan Subprefecture" (噶瑪蘭廳; Kat-má-lán Thiaⁿ) was at the present day location of Yilan City. Construction of the city wall was completed a year later. After a few years once the basic infrastructure was ready, the city assumed the political, economical, cultural and educational center for the Lanyang Plain. In 1878, Komalan was a large rice production area commonly called Kapsulan, and became a district called Gilan Hsien. It was one of the three new districts that constituted the new Taipeh Prefecture.
According to the 1904 census, the population of Giran town was about 15,000.
After the handover of Taiwan from Japan to the Republic of China on 25 October 1945, Yilan City was created in January 1946 as a county-controlled city the county seat of the newly created Yilan County and continue to become the political, economical and cultural centers of the region.
