Clarence Steven McGann (June 28, 1951 – May 24, 2023)[1][2] was an American diplomat who served as the United States Ambassador to Fiji, Kiribati, Nauru,[3] Tonga, and Tuvalu from 2008 to 2011.

His achievements centered on democracy-building, law enforcement cooperation, maritime security, humanitarian assistance, disaster response and the largest expansion of U.S. diplomatic presence in the Pacific with the construction of Embassy Suva as a regional hub post.

McGann launched a series of negotiations that led to ship-rider agreements with eight Pacific Island Countries and the U.S. Coast Guard to prevent unlicensed commercial fishing and protect local economies.

He also served as a Senior Adviser in the Bureau of East Asian and Pacific Affairs as an expert on North Korean human rights and refugee issues (2005–2006).

He also guided the UN Security Council resolution that endorsed Nelson Mandela as Special Envoy for Burundi and worked directly with the former South African President to determine his mandate (UNSCR 1286).
