OV-fiets is a nationwide bike-sharing program in the Netherlands. The system has 22,000 bikes in 282 locations mainly train stations, all over the country. A membership is required and requires the use of an OV-chipkaart. The program, which started on a small scale in 2003, has enjoyed a steadily increasing popularity with over 5.9 million rides registered in 2024.

The program's interconnection with the public transport network allows the country's many bicycle owners to use that network for part of their trip.
