Berlin Karl-Bonhoeffer-Nervenklinik is a railway station in the Reinickendorf borough of Berlin, Germany. It is served by the Berlin S-Bahn, the line of the Berlin U-Bahn and named after the adjacent homonymous psychiatric hospital in Wittenau. The namesake psychiatrist Karl Bonhoeffer (1868–1948) was the father of the resistance fighters Klaus and Dietrich Bonhoeffer. Whereas the hospital and the underground station are located in the locality of Wittenau, the S-Bahn station happens to be in the adjacent Reinickendorf, both localities of the Reinickendorf borough.
