Trzcińsko-Zdrój [ˈtʂt͡ɕiɲskɔ ˈzdrui̯] (German: Bad Schönfließ; Kashubian: Szénflét) is a town in Gryfino County, West Pomeranian Voivodeship, Poland, with 2,591 inhabitants (2005).

The town probably originated from a Pomeranian settlement at an important trading route between Poznań and the Baltic Sea and has been a commercial centre ever since.

Poland was to buy and re-incorporate the town and its surroundings,[3] but eventually the Luxembourgs sold it to the Teutonic Order, whose rule lasted until 1454.

After the Napoleonic wars, economic development accelerated, and with the growth of the town, extra gates were broken into the old fortifications, parts of which were removed.

Mud baths opened in Schönfliess in the late 19th century, and the town became a health resort and gained the official title Bad in 1907.
