The Las Cabañas Bridge () is a historic highway bridge in Adjuntas municipality, Puerto Rico. Built in 1919 to provide access to a key coffee-producing region, it was financed by nearby plantations through public subscription. Designer Rafael Nones and builder Félix Benítez Rexach, two of the most prominent figures in Puerto Rican bridge construction in the early 20th century, used a unique combination of steel and concrete technologies to produce a girder design unlike any other on the island and possibly beyond. The bridge was added to the U.S. National Register of Historic Places in 1995.
