Christoph Ingenhoven (born 1960) is a German architect based in Düsseldorf, known for buildings designed around daylight, natural ventilation and low energy use, an approach he calls "supergreen". Born in Düsseldorf, he studied at RWTH Aachen and, for a year, with Hans Hollein at the Kunstakademie Düsseldorf, and founded his office in the city in 1985. He drew wide notice in 1991, when his team shared the jury prize with Norman Foster in the competition for the Commerzbank Tower in Frankfurt, and international recognition with the RWE Tower in Essen (1997), one of the world's first ecological high-rise buildings. He received the European Prize for Architecture in 2022.

The Lanserhof Sylt (2022) won both MIPIM and WAF awards in 2023.
