Haim Hanani (11 September 1912 as Chaim Chojnacki– 8 April 1991) was a Polish-born Israeli mathematician, known for his contributions to combinatorial design theory, in particular for the theory of pairwise balanced designs and for the proof of an existence theorem for Steiner quadruple systems. He is also known for the Hanani–Tutte theorem on odd crossings in non-planar graphs.

(pl) Haim Hanani (* als Chaim Chojnacki am 11. September 1912 in Slupca; † April 1991) war ein israelisch-polnischer Mathematiker, der sich mit Kombinatorik befasste. Hanani studierte an den Universitäten Wien und Warschau Mathematik mit dem Abschluss in Warschau 1934. 1935 ging er nach Palästina und war der erste, der an der Hebräischen Universität 1938 in Mathematik promoviert wurde. Er kämpfte für die Unabhängigkeit Israels in der Hagana und war deshalb von den Briten inhaftiert. 1955 wurde er Professor am Technion. 1969 bis 1973 war er der erste Rektor der Ben-Gurion-Universität des Negev.
