Garry Mauro (born February 21, 1948) is an American politician who served four terms as Land Commissioner of Texas from 1983 to 1999, during the administrations of Governors Mark White, Bill Clements, Ann Richards, and George W. Bush.

He is also known for losing the 1998 Texas gubernatorial election in a landslide to Bush, who at the time was the incumbent governor seeking re-election.

He moved for exceptionally low interest rates, which led to a record number of housing loans for Texas veterans.

The bill requires fleet operators in larger cities to convert to clean-burning fuels, including compressed natural gas.

Mauro was appointed by Speaker Jim Wright to a Task Force that put similar measures in the re-authorization of the Clean Air Act.

In 1993, President Bill Clinton appointed Mauro to be the Chairman of the Federal Fleet Conversion Task Force for Alternative Fuels which further implemented those measures.

Mauro convinced the U.S. Senate to ratify the Annex V provision of the MARPOL Treaty, which outlaws the dumping of plastic items in the world's oceans.

In 1991, Mauro played a key role in gaining passage of the Oil Spill Prevention & Response Act which makes the land office the lead state agency for spills in state waters, and coastal management legislation which gives the Land Office a strong hand in matters of environmental consequence along the coast.
