Dominika), is an annual cultural and trade event organized between July and August in the port city of Gdańsk, Pomeranian Voivodeship, Poland.

It was founded in 1260 and together with Weihnachtmarkt and Oktoberfest, it is considered one of the biggest cultural and trade open-air events in Europe attended by 5-8 million national and international visitors annually.

At first, it was held at the Dominic Square but, as the event developed, it needed greater space, so the Fair was moved into the area of Wały Jagiellońskie and Długa Streets.

It was possible to buy famous Toruń gingerbreads, Kashubian ceramics, Czech glass, Eastern furs and carpets, English cloth, gypsy pots, Goldwasser (type of vodka) and amber.

In 1972, owing to the efforts of Wojciech Święcicki, a journalist from a popular Gdańsk evening paper Wieczór Wybrzeża, the tradition of the Fair was restored.

Every year, about 1000 merchants, artists, artisans and collectors take part in the Fair, and it is visited by an average of 70,000 people daily, whose number usually doubles at weekends.

One can find there an abundance of food stalls offering cold beer, meat, potatoes, sausages, and shish kebabs baked on a gridiron.

The halls of mirrors have disappeared and nobody cuts women into two pieces with a handsaw during magic shows; however, it still remains one of the main attractions for the youngest participants of the St. Dominic's Fair.
