The 1873 Landis Mill Covered Bridge is a covered bridge that spans Little Conestoga Creek in Lancaster County, Pennsylvania, United States. A county-owned and maintained bridge, its official designation is the Little Conestoga #1 Bridge. The bridge, built-in 1873 by Elias McMellen at a cost of $969, is today surrounded by development, a shopping center, and highways on the boundary of Lancaster, Pennsylvania. At 53 feet, it is the shortest covered bridge in the county, with a width of 13 feet, an overhead clearance of 10 ft. 6 inches, and an under clearance of 8 ft.

Builder Elias McMellen, who built many of Lancaster's covered bridges using the Burr arch-truss, chose to build this short bridge using a simpler design. The bridge has a single-span, wooden, double pyramidal-shaped Burr-type truss and multiple king post truss design with the addition of steel hanger rods. It is the only bridge in the county to use this design. The deck is made from oak planks. It is painted red, the traditional color of Lancaster County Covered Bridges, on both the inside and outside. Both portals to the bridge are painted in red with white trim.

In 1980 it was added to the National Register of Historic Places.
