Stanisławów was founded as a fortress and was named after the Polish hetman Stanisław "Rewera" Potocki.
Some sources claim it was named after his grandson Stanisław.
Following the First Partition of Poland in 1772, the name was transliterated as Stanislau in German, as the city became part of the Austrian Empire (future Austria-Hungary); however, after the revolution of 1848, the city carried three different linguistic renderings of its name: German, Polish, and Ruthenian (German: Stanislau, [ˈʃtaːnɪslaʊ]; Polish: Stanisławów, [staɲiˈswavuf]; Ukrainian: Станісла́вів Stanislaviv, [stɐn⁽ʲ⁾iˈslɑwiu̯], or Станиславiв Stanyslaviv, [stɐnɪˈslɑwiu̯]).
Other spellings used in the local press media included Russian: Станиславов and Yiddish: סטאַניסלאוו‎.
After World War II it was changed by the Soviet authorities into a simplified version Stanislav (Ukrainian: Станісла́в, [stɐn⁽ʲ⁾iˈslɑu̯]; Russian: Станисла́в, [stənʲɪˈslaf]).
In 1962, on the city's 300th anniversary, it was renamed to honor the Ukrainian writer Ivan Franko.
Due to the city's wordy name, unofficially it is sometimes called simply Franyk (Франик) by its residents.
Even though Ivano-Frankivsk is the officially accepted name, the city's original name has never been fully abandoned and/or forgotten and can be found throughout the city in all kinds of variations.

The name of the city was altered several times through the centuries.
It was founded as Stanisławów; but in 1772 transliteration changed to Stanislau, in 1919 to Stanislaviv and again to Stanisławów.
In 1939 transliteration changed to Stanislav, in 1941 to Stanislau, in 1944 again to Stanislav.
And finally, on November 9, 1962, the name was officially changed by the First Secretary Nikita Khrushchev, reportedly as an honour to poet Ivan Franko.
