Adorno-Ampel, Traffic signal and tourist site at Senckenberganlage, Frankfurt, Germany

The Adorno-Ampel is a pedestrian traffic light on Senckenberganlage in Frankfurt, installed in 1987 at the crossing between the Bockenheim campus of Goethe University and the Institute for Social Research. It is a standard signal with red and green phases for pedestrians and vehicles, named after Theodor W. Adorno, who had campaigned for a safe crossing since 1958.

The Institute for Social Research moved to Senckenberganlage in 1951. On 12 March 1958 Adorno wrote to the university rector about crossing dangers; police chief Gerhard Littmann then had a zebra crossing marked. After a fatal accident and one involving Adorno's secretary in 1962, he demanded signals in the Frankfurter Allgemeine Zeitung. The light was installed in 1987 under institute director Ludwig von Friedeburg, 18 years after Adorno's death.

The name was applied by the public as soon as the light went up in 1987, even though its installation had no causal link to Adorno's 1962 reader's letter. The Frankfurter Rundschau called it an "Adorno memorial" that year, sixteen years before the official Adorno monument was inaugurated in 2003. René Pollesch's play Je t'adorno, premiered at the Schauspiel Frankfurt in 2014, uses the light as a leitmotif and quotes Adorno's call for a pedestrian signal.

The light stands on Senckenberganlage at the corner of Dantestrasse, on the route between the university campus and the Institute for Social Research. Pedestrians cross the multi-lane street here at signal control; the crossing is at street level and reached on foot from either sidewalk.
