The Conrad N. Hilton Foundation is an American non-profit charitable foundation, established in 1944 by hotel entrepreneur Conrad Hilton. It remained relatively small until his death on January 3, 1979, when it was named the principal beneficiary of his estate. In 2007, Conrad's son, Barron Hilton announced that he would leave about 97% of his fortune^[2] to a charitable remainder unitrust which names the foundation as the remainder beneficiary.^[2][3]

The foundation's assets, as of September 2019, were approximately $2.9 billion and had increased to $6.3 billion due to Barron Hilton's passing.^[4] Since inception, the foundation has awarded more than $1.7 billion in grants. Currently more than 50% supports international charitable projects.^[5] According to the OECD, the foundation's financing for 2019 development decreased by 11% to US$42.3 million.^[6]

The foundation's mission is derived from the last will and testament of Conrad Hilton that directs the organization to "relieve the suffering, the distressed, and the destitute."^[7] The foundation invests in seven program areas: Catholic sisters, disaster relief and recovery, foster youth, homelessness, hospitality workforce development, safe water, and young children affected by HIV and AIDS. The foundation also supports organizations in four transitioning program areas: avoidable blindness, Catholic education, multiple sclerosis and substance use prevention.^[8]

The Conrad N. Hilton Humanitarian Prize is awarded annually by the foundation. It was inaugurated in 1996 and is the largest humanitarian award in the world. Its annual award of USD 1.5 million was increased in 2015 to 2 million to commemorate its 20th Hilton Humanitarian Prize laureate, Landesa.^[10]

Conrad Hilton's granddaughter, Hawley Hilton McAULIFFE, became chair of the board January 2021, superseding Steven M. Hilton, who was the chairman of the organization for most of its existence. He started working at the foundation in 1983 and served as its CEO from 2005 to 2015.^[19] Hilton retired as president and CEO, and was succeeded by Peter Laugharn.^[20][21] In his retirement announcement, Hilton said, “When I joined the Hilton Foundation in 1983, I couldn’t imagine the path that lay ahead. At that time, a handful of staff guided about $6 million in grants annually. Fast forward to today, and we have grown to a staff of over 50 and have awarded over a billion dollars in grants to improve the lives of disadvantaged and vulnerable people around the world.”^[22] Peter Laugharn began his tenure as president and CEO on January 1, 2016.^[23]
