Peter Paddleford (1785–1859) was a covered bridge builder who designed a new wooden bridge truss, one he never patented. The design was used widely throughout New Hampshire, Maine, and Eastern Vermont during much of the 19th century. Paddleford was also a millwright.
Peter Paddleford was born in Enfield, New Hampshire on September 14, 1785. He moved with his father, Philip, to Monroe, New Hampshire, in the early 1800s. In 1816, the younger Paddleford was issued US Patent 2,594X. The spinning device patented is not recorded as having been produced. In 1930 Peter moved to Littleton, New Hampshire, where he spent most of his remaining years.
In 1833, Paddleford unsuccessfully participated in a bid to build a bridge from Montreal, Quebec. island. In other bridges, Paddleford first utilised the Long truss design, but later created his own. This was challenged by others, who thought that Paddleford had stolen from the earlier designer. Paddleford never recorded his patent and it was used by others. His truss "superficially resembles the Long truss", but they had different purposes. Paddleford's design saw wide use, especially in New Hampshire, Orleans County, Vermont, and Caledonia County, Vermont.
His first self-designed bridge was possibly Joel's Bridge in Conway, New Hampshire, which was constructed in 1846, working in partnership with his son Philip. Peter Paddleford retired in 1849, although Philip continued to build bridges. Paddleford died on October 18, 1859.

The unpatented Paddleford Truss is only found in New England, The truss was designed by Peter Paddleford of Littleton, N.H. who had previously erected Long truss bridges. About 1846, he remodeled this design by replacing the counterbraces with a stiffening member fastened to the inside of the posts at points near the top and bottom chords. This resulted in an unusually strong and rigid structure. Other local builders became interested, and a considerable number were erected."
