Shai Davidai (born 1983 or 1984) is an Israeli former assistant professor of business at Columbia Business School known for his outspoken advocacy for Israel and against the Columbia University pro-Palestinian campus protests and occupations during the Gaza war. After the October 7 attacks on Israel and subsequent Gaza war, Davidai's pro-Israel activity led him into conflict with Columbia University students, faculty, and administrators. He was temporarily suspended from the university for alleged harassment of faculty. An investigation into his conduct ended without a conclusion, and he left Columbia in July 2025.
