The Siemens S70 and its successor, the Siemens S700, are a series of articulated low-floor light-rail vehicles (LRV) and modern streetcars manufactured for the United States market by Siemens Mobility, a division of German conglomerate Siemens AG. The series also includes a European tram-train variant, the Siemens Avanto.

The S70 was manufactured from 2002 to 2017 and the improved S700 from 2014 to present, but the latter model designation was only introduced in 2019 and then retroactively applied to certain versions of the S70 built in earlier years.[2] In this market, it competes mainly with Alstom and Kinki Sharyo low-floor LRVs and streetcars manufactured by Brookville and Inekon.

The Avanto was built for the European market starting in 2006 and was principally sold to tram-train systems which, in whole or part, share their tracks with heavy rail trains. In Europe, the Siemens Combino and Avenio models are the preferred offerings for purely light rail or tramway systems. In the tram-train market, its principal competitors are Alstom's Flexity and Citadis, as well as CAF's Urbos series.
