Rennweg is a medieval main road and is today part of the inner-city pedestrian zone of Zürich, Switzerland.

Today, as well as the Limmatquai, as well as Augustinergasse, it is a section of the southern extension of the Seeuferanlage promenades that were built between 1881 and 1887.

Archaeologists excavated individual and aerial finds of the Celtic-Helvetii oppidum Lindenhof from around the 1st century BC La Tène culture, whose remains were discovered in archaeological campaigns in the years 1989, 1997, 2004 and 2007 on Lindenhof, Münsterhof and Rennweg,[3] and also in the 1900s, but the finds mistakenly were identified as Roman objects.

Not yet archaeologically proven, but suggested by the historians, as well for the first construction of the today's Münsterbrücke Limmat crossing, the present Weinplatz square was the former civilian harbour of the Celtic-Roman Turicum, and so the term Weinplatz may have kept its ancient meaning wine square.

The Rennweg respectively former Rennweg–Augustinergasse stop on lines 6, 7, 11 and 13 of the Zürich tram system is some 80 metres (87 yd) further southernly along the Bahnhofstrasse road.
