Bad Vilbel (German: [baːt ˈfɪlbl̩] ⓘ) is a spa town in Hesse (Hessen), Germany, famous for its many mineral water springs.

Bad Vilbel is the largest town in the Wetteraukreis district and part of the Frankfurt Rhein-Main urban area with its city center being located 8 km northeast of downtown Frankfurt am Main at the banks of the river Nidda.

The health spa operations stopped in the 1960s but the mineral water industry connected more springs of the Wetterau by pipelines to the bottling plant of Hassia in Bad Vilbel.

The Current Mayor is Sebastian Wysocki (born 1985) of the Christian Democratic Union of Germany (CDU).

Furthermore, Bad Vilbel has several local bus lines called Vilbus connecting the city center to the neighborhoods.
