Fortuño, Luis G. (Luis Guillermo), 1960-

Luis Guillermo Fortuño Burset (born 31 October 1960) is a Puerto Rican politician. He notably served as Resident Commissioner of Puerto Rico from 2005 to 2009 and as Governor of Puerto Rico from 2009 to 2013.

Born in San Juan, he graduated from Colegio Marista in Guaynabo, Puerto Rico before earning a B.S. from the Edmund A. Walsh School of Foreign Service at Georgetown University and a J.D. from the University of Virginia School of Law. After working as a lawyer in private practice, Fortuño served as the first secretary of economic development and commerce of Puerto Rico (1994–1997), as the executive director of the Puerto Rico Tourism Company (1993–1994), and as the president of the Puerto Rico Hotel Development Corporation during the administration of Pedro Rosselló. In 2004, Fortuño was elected resident commissioner of Puerto Rico, defeating Senator Roberto Prats. As resident commissioner, Fortuño represented Puerto Rico in the United States House of Representatives from 2005 to 2009; during his tenure, he served as Chair of the Congressional Hispanic Conference, as a Member of the newly created United States House Natural Resources Subcommittee on Insular Affairs and as co-chair of the Friends of Spain Caucus.

Fortuño won the 2008 PNP gubernatorial nomination by a wide margin after defeating former governor and then-senator Pedro Rosselló in the primaries. He then won the general election by a comfortable margin, defeating incumbent governor Aníbal Acevedo Vilá. Fortuño has served as president of the New Progressive Party of Puerto Rico (PNP), the Council of State Governments, and the Southern Governors Association. Fortuño sought to be re-elected as governor in the 2012 elections, but was defeated in by Alejandro Garcia Padilla.

Fortuño moved to Washington, D.C. in early 2013 where he is a partner with the Steptoe & Johnson law firm. He served as Shadow Member of the U.S. House of Representatives from Puerto Rico from 2017 until 2021.
