Lindenhof, lit. 'Tilia Courtyard', in the old town of Zurich, Switzerland, is the historical site of a Roman castle, and the later Carolingian Kaiserpfalz. It is situated on Lindenhof hill , on the left side of the Limmat river at the Schipfe.

In 1747, a second-century Roman tombstone was discovered at the site, bearing the oldest attestation of Turīcum, the Roman-era name of Zurich, as STA[tio] TURIC[ensis], at the time a tax-collection point. The castle remained intact during the early phase of Alemannic immigration in between the fifth and sixth centuries, but was derelict by the ninth century, when it was rebuilt as a residence for Louis the German. It later became dilapidated and used as a source of building stone by the 13th century.

The Lindenhof remained a place of civil assembly into modern times.
