Navibus is a group of water bus routes in the French city of Nantes, operated as part of the Tan urban transit network that also includes buses and trams. Routes operate on both the River Loire and the River Erdre, and accept the full range of standard Tan tickets. The current services date back to an initial trial service on the River Loire in 2005. Historically, services were operated on the River Loire between 1887 and 1958 by a flotilla of eight steam boats known as roquios.
