The 1921 Parvin Bridge, also known as Lost Creek Bridge, is a covered bridge located in Lane County, Oregon. This single-lane 75-foot (23 m) bridge crosses Lost Creek, a tributary of the Middle Fork Willamette River, near the 1880s homestead of early pioneer settlers James and Salina Parvin. Parvin ran a store, served as postmaster for eleven years, and was also active in the Dexter church.

This 1921 bridge was a replacement for a 1880s 66-foot (20 m) Howe truss design, which failed a 1917 inspection by bridge inspector J. W. McArthur. He wrote, "An old bridge. Chords were badly worm-eaten. One chord has been reinforced in the middle by a timber bolted on. Wood is but little better than a powder from worm action. All signs indicate a new bridge in from 2 to 4 years."

George W. Breeding constructed the present bridge at the same site in 1921 for $3,617, equivalent to $63,800 today. The new Howe truss bridge includes a 62-foot (19 m) eastern approach and a 17-foot (5.2 m) western approach. Roadwork in the mid-1970s realigned the road to bypass the bridge, making it accessible only to pedestrians afterward. However, a renewed interest in Oregon's covered bridges prompted Lane County to renovate and reopen the bridge to vehicular traffic in 1986. The granddaughters of James and Salina Parvin attended the re-dedication ceremony.

In 1996, OBEC Consulting Engineers installed a new roof, replaced some supports, and added new bridge rails, siding, and paint. The bridge was raised an additional foot for increased clearance from river debris and has a 10-short-ton (9,100 kg) load limit and a maximum height of 11 feet 11 inches.

The Parvin Bridge was listed on the National Register of Historic Places in 1979.
