Work on establishing a new flag for the town and municipality of Prudnik began in the 1990s. In 1997, the Polish Heraldry Center developed two flag designs for Prudnik. The first design divided the flag into three horizontal stripes: red, a narrower yellow one, and a wider blue one. The second design featured a two-colored flag in red and light blue. On June 18, 1998, the Prudnik Town Council adopted the red and light blue flag.

Prudnik's first municipal flag was introduced during the German era. It consisted of two horizontal stripes reflecting the colors of the town's coat of arms at the time: white on top and red on the bottom. White and red were the colors of the Czech House of Rosenberg, a member of which—Wok of Rosenberg—founded Prudnik. Use of the flag was discontinued in 1945, following World War II.

The oldest form of the Prudnik coat of arms is presented on a wax seal affixed to a document from 1399, regarding the city council's obligation to pay 10 marks in silver for the chapel of St. Jadwiga in Prudnik.
On the blue background is an open gate flanked by red towers with silver roofs. In the middle is the golden eagle of the Silesian Piasts.
The Austrian Emperor Maximilian II allowed the city to seal documents with red wax.
This distinction gave the city the right to appoint as a witness every citizen before the court, with the exception of the clergy.
In 1607 Emperor Rudolf II, for his faithfulness, enriched the coat of arms of Prudnik. He allowed to add the silver coat and the golden Czech lion over the current coat of arms together with the repeated motif of the wall.
The current version of the coat of arms has been used again since 1990.
