Kazimierz Dolny is a small historic town in east-central Poland, on the right (eastern) bank of the Vistula river in Pulawy County, Lublin Voivodeship. Historically it belongs to Lesser Poland, and in the past it used to be one of the most important cities of the province.

It is a considerable tourist attraction as one of the most beautifully situated little towns in Poland. It enjoyed its greatest prosperity in the 16th and the first half of the 17th century, due to the trade in grain conducted along the Vistula. It became an economic backwater after that trade declined, and this freeze in economic development enabled the town to preserve its Renaissance urban plan and appearance. Since the 19th century it has become a popular holiday destination, attracting artists and summer residents.

Kazimierz Dolny is an art center in Poland. Many painters retreat to this small town to paint and sell their work. Galleries can be found in almost every street, offering for sale sculptures, stained-glass, folk art, and fine art.

The town is one of Poland's official national Historic Monuments (Pomnik historii), as designated September 16, 1994 and tracked by the National Heritage Board of Poland.

Kazimierz Dolny is located on the eastern bank of the Vistula, at the edge of historical Lublin Upland extending further east from Malopolska Upland to the west. It owes its picturesque location to the Lesser Polish Gorge of the Vistula. The town is part of the so-called tourist triangle Pulawy – Kazimierz Dolny - Naleczów. It does not have a rail connection, the nearest station is located in Pulawy (Pulawy - Miasto).
