Hans Mossel (August 28, 1908 – July 20, 1944) was a Dutch chess master and bridge player. Born in Rotterdam, Netherlands, Mossel was recognized as one of the strongest amateur chess players in the country during the 1930s.
Mossel was noted for his sharp, often attacking style of play and was a regular participant in significant Dutch chess tournaments. While he did not win the official Dutch Chess Championship, he consistently performed well and engaged in competitive matches against leading national and international players, including the future World Champion Max Euwe. He was an active member of the Rotterdamse Schaakvereniging (Rotterdam Chess Association). Beyond his chess prowess, Mossel also achieved recognition for his skills in contract bridge.
As a Jewish individual, Hans Mossel became a victim of the Holocaust. He was arrested during the German occupation of the Netherlands and subsequently deported to Auschwitz concentration camp, where he was murdered on July 20, 1944, at the age of 35. His life and tragic death represent one of the many personal stories of the persecution and genocide faced by Jewish communities during World War II.
