The Taylor Mill State Historic Site is a historic area and state park in Derry, New Hampshire. It features and preserves the site of the ?Taylor Up and Down Sawmill? which was established in 1799.

Named after Robert Taylor who was the creator of the said sawmill over two hundred years ago, the Taylor Mill State Historic Site is located inside the Ballard State Forest. It features a functioning and reconstructed sawmill, similar to the original one. The current one on the site was actually rebuilt from parts recovered all throughout New England, completed through the efforts of Ernest R. Ballard and his wife.

Like many other state parks in New Hampshire, the Taylor Mill Historic Site is only seasonally open. It operates on weekends of the summer months.
