The first mentioning of the settlement is found in a court note of 2 January 1482 which indicated that Morshyn and surrounding villages belonged to a nobleman Juchno Nagwazdan and was part of the Kingdom of Poland. In 1538 Morshyn owners, the Branecki family, who became interested in local industry which was a salt mining have acquired a permission from the royal chancellery on opening of salt mines. Five mine wells were dug out for brine extraction. However, the business did not justify itself as the Morshyns salt was bitter and unfit for consumption. The salt industries fell into decline. In the second half of 17th century Morshyn remained a poor village. In 1692 Morshyn accounted for 12 yards. The settlement was changing hands and often was transferring between owners. Following the first partition of Poland in 1772, Morshyn went to the Austrian Empire. With construction of railroad Stryj—Stanislawow through Morshyn, a life has revived in the village. Since 1878 Morshyn is known as a spa resort. The first chemical analysis of mineral water was published by a professor of the Lviv University W.Radziszewski in 1881. About therapeutic properties of the Morshyn's brine at that time wrote by many researchers, comparing it with waters of famous then German, Hungarian, and Czech resorts. In 1918-1939 Morshyn was in Polish territory and, as "Morszyn-Zdrój," was a popular spa. The spa belonged to the Medical Association from Lviv, in late 1920s almost 1000 guests came there yearly. During the times when western Ukraine was under Polish authority, the city was part of the Ivano-Frankivsk regional administration, Stanisławów Voivodeship back then. Currently the town is located in the close proximity to Ivano-Frankivsk Oblast and Carpathian Mountains. Currently the city is one of the major national tourist resort as well as health resorts.
