Janney Furnace Park, 19th-century blast furnace ruins in Ohatchee, United States.

Janney Furnace Park surrounds a 50-foot stone blast furnace chimney in Ohatchee, Alabama, the remnant of an 1863 ironworks built by Alfred Janney. The chimney stands beside the Calhoun County Confederate Memorial, a black granite monument erected in June 2003, and the 2009 Confederate and Native American Museum.

Alfred Janney built the furnace in 1863 to produce pig iron, using the iron ore found on the site. In July 1864 a Union raid destroyed everything except the stone chimney, which still stands. The furnace was listed on the National Register of Historic Places in 1976.

The site honors the legacy of its founder Alfred Janney through displays connected to the ironworks operation and local communities of the 1860s. Visitors encounter stories of the people who worked here and the broader context of industrial life in the region during that era.

The grounds are walkable and open for exploration from all sides, with informational markers explaining the features of the site. Visitors should wear comfortable shoes and be prepared for uneven terrain and steps as they move around the ruins and into the museum area.

The furnace's stone chimney is the only part of the 1863 ironworks that survived the July 1864 Union raid, which destroyed the rest of the operation. The surrounding Calhoun County Confederate Memorial, erected by the Sons of Confederate Veterans in June 2003, is described as the world's largest black granite Confederate memorial.
