St. Nicholas' Church in Bączal Dolny, Poland, was a Gothic church from the seventeenth-century. Since the 1970s, the church was part of the Museum of Folk Architecture in Sanok.
The temple illustrated a typical Lesser Polish wooden church's architecture, and was one of the most prized buildings of religious heritage in south-eastern Poland. The rector of the church from 1939 to 1948 was Florian Zając, a chaplain of the Home Army.
The church was completely destroyed by a fire at the Museum of Folk Architecture, Sanok in the early morning hours of 16 August 2026.
