The Zeil (German: [ˈtsaɪl]) is a street in the city centre of Frankfurt, Germany.

The name, which dates back to the 14th century, is derived from the German word Zeile "row" and originally referred to a row of houses on the eastern end of the north side; the name was not extended to the entire street until later.

The western part of the Zeil is a pedestrian zone between two large plazas, Hauptwache in the west and Konstablerwache in the east.

These two plazas serve as major intersections for underground trains, trams and buses.

This brought drastic changes for motorists because the route via Hauptwache, which is an important north-south connection for individual traffic, was closed.
