Selahattin Ülkümen was a Turkish diplomat who was recognized by Israel as one of the Righteous Among the Nations in 1989, with his name being listed at Yad Vashem in the city of Jerusalem. During World War II, he was serving as a consul-general of Turkey on the island of Rhodes, Greece, which had been invaded and occupied by Nazi Germany. Ülkümen assisted the island's Jews by personally intervening to prevent as many of them as possible from being deported by the Germans amidst the Holocaust. In total, he managed to save around 50 Jews—13 on the basis of their Turkish citizenship, and the remainder through his own initiatives.

Righteous Among the Nations is an honourific used by the State of Israel to describe all of the non-Jews who, for purely altruistic reasons, risked their lives in order to save Jews from being exterminated by Nazi Germany during the Holocaust. The term originates from the concept of ger toshav, a legal term used to refer to non-Jewish observers of the Seven Laws of Noah.
