The New Hope Mills Complex is a historic grist mill complex located on Glen Haven Road near the intersection with Route 41A in the hamlet of New Hope in the town of Niles in Cayuga County, New York.

In 1919 it was sold to W. E. Rounds and A. Ryan,[3] and it remained in the Rounds family until 1947, when it was sold to Howard Weed, Hubert Latta, and Leland Weed and renamed the New Hope Mills.

Water could be stored in the upper pond to be used to run the mill the next day.

[2] The New Hope Mills company, which produces pancake, muffin, scone and cookie mixes, moved its manufacturing operations to nearby Auburn, New York, in 2003,[5] but still owns the old mill and preserves it with the intention of converting it into an operating museum.

[2] The New Hope Mills Complex was listed on the National Register of Historic Places in 2005.
