Henning Albert Boilesen (15 February 1916 – 15 April 1971) was a Danish business executive who lived in Brazil. He was the president of Ultragaz and founder of CIEE - Centro de Integração Empresa Escola. He was an allegedly supporter of the governmental repression against leftist clandestine organizations during the Brazilian military dictatorship. Boilesen was killed by militants from Movimento Revolucionário Tiradentes (MRT) and Ação Libertadora Nacional (ALN) on April 15, 1971 in the city of São Paulo, in a planned reprisal for his involvement in the repression.
