Herzmansky was a department store in Vienna. It was founded by the Austrian Silesian merchant August Herzmansky [de] in 1863. The department store was located at Mariahilfer Strasse 26–30 / Stiftgasse 3 in the 7th district of Vienna, Neubau. A branch of the Peek & Cloppenburg chain has been in its place since 1998.

The store became the largest drapery/department store in the Austro-Hungarian Empire by 1892. After August's death, his nephews and later other relatives took over the management, with various expansions and renovations taking place over the years. Shortly before the Nazis came to power, the company was sold to the Austrian Jewish merchant Max Delfiner. The store was "Aryanized" during the Nazi period but was later returned to its rightful owner, Max Delfiner, in 1948. After several changes in ownership, mergers, and modernizations, the Herzmansky department store closed in 1997. The site was sold to the Düsseldorf fashion chain Peek & Cloppenburg in 1998, ending the Herzmansky department store's long history. The original building on Stiftgasse still stands, preserving its exterior appearance.

August Herzmansky, who originated in Odry in what is now the Czech Republic, opened a general store in 1863 in the 7th district at Kirchengasse 2. The concept was well received by the shopping public due to its upscale product range and fixed prices. By 1892 Herzmansky was the largest drapery/department store in the Austro-Hungarian Empire.

Architect Maximilian Katscher built the new building at Stiftgasse 3 between 1896 and 1897. This five-storey building was erected on a deep parcel of land (with a wrought-iron structure). A courtyard was designed in the middle with pillars (with stucco covering) and columns (covered with synthetic marble). At the end of the courtyard was a two-branched three-tier main staircase (also of wrought-iron), which was demolished in 1963. Two more staircases connected the building with another courtyard and a neighboring building. The ground and first floors were supported by the aforementioned limestone pillars, the second and third floors by marble pillars (made from Istrian Smerique marble).

The expansion of the business led to Herzmansky having five locations by 1917.

After the death of the company's founder, his nephews Johann (1857–1924) and Eduard Herzmansky (1852–1911) took over the management of the company, but were unable to continue their uncle's success. During this period, Gerngroß department store, which had originally partnered with Herzmansky, established himself with a dominant Art Nouveau building (1904) on Mariahilfer Strasse, which had become the main shopping street of Vienna. In 1906, the nephews left the business. A relative by marriage, Johann Falnbigl (1866-1932), took over the management and became a partner. Major extensions were built in 1908 and 1928 during Falnbigl's management. After Falnbigl's death on 7 February 1932, his son Wilfried took over the management for a short time, but left the partnership in 1933. Max Delfiner was the sole owner of the Herzmansky company from 1933 to 1938.

With the Anschluss, the store was "Aryanized" in favor of the Dornbirn-based textile producers Rhomberg and Hämmerle, and the previous Jewish owners had to emigrate. In the period 1938–1940, the purchase of the property at Mariahilfer Strasse 30, giving increased frontage to a thoroughfare with greater footfall, led to an expansion of the sales area and the number of employees to 700 people.

The battle for Vienna in April 1945 caused considerable destruction. On the night of 12-13 April 1945, two Herzmansky stores fell victim to the fires, but operations resumed on 15 May 1945.
