David Mauricio Rivera (born September 16, 1965) is an American Republican politician from Florida. He was a member of the U.S. House of Representatives for one term, representing parts of South Florida from 2011 to 2013.

Rivera was arrested on December 5, 2022, and charged with failure to register as a foreign agent and money laundering conspiracy.

Rivera was born in New York City on September 16, 1965, and moved to Florida in 1974. Both his father, a cab driver, and his mother Daisy, a driving instructor, had fled Cuba after the political rise of Fidel Castro. He graduated from Miami Christian High School. He earned his Bachelor of Arts degree with honors in Political Science from Florida International University in 1986 and his MPA in 1994.

After college, Rivera worked as Public Affairs Director for the Washington D.C.–based Valladares Foundation, an international human rights NGO. The organization was founded by U.S. Ambassador Armando Valladares, the former U.S. Ambassador to the United Nations Human Rights Commission. Then, he worked for the Office of Cuba Broadcasting managed by auspices of the U.S. State Department. He has also been an adjunct professor in the FIU School of Policy and Management. His articles on U.S.–Cuba relations have been published in The Miami Herald and El Nuevo Herald.

In 2002, he ran for Florida's 112th state house district. He defeated Ray Gonzalez in the Republican primary, 52–48%. He won the general election unopposed. He won re-election unopposed in 2004, 2006, and 2008.

In the Florida House, Rivera chaired the rules committee before serving as chairman of the appropriations committee from 2009 to 2010, where he pushed to create new professional schools at FIU and helped the Miami-Dade delegation work within a tight state budget. “We are all geared toward finding cost savings,” he explained to the Herald. Alongside his support for tax-free back-to-school shopping holidays, Rivera sponsored a measure forbidding places of higher education in Florida from sponsoring and paying for research trips to Cuba. And it was Cuba, perhaps more than any other issue that emerged as Rivera’s main issue concern in Tallahassee: “It’s the most important issue to me,” he said in the winter of 2004. “I think every Cuban American from whatever walk of life has a moral obligation to continue the cause of a free and Democratic Cuba.

In addition to his legislative office, he has served the Republican Party as State Committeeman for the Republican Party of Florida and as the Executive Director for the Republican Party of Miami-Dade County.

In January 2009, Rivera filed to run for the state senate seat being vacated by J. Alex Villalobos. However, when neighboring U.S. Congressman Lincoln Díaz-Balart decided not to run for another term in 2010, his brother, U.S. Congressman Mario Díaz-Balart, opted to run for a new term in Lincoln's district rather than his current one. This created an opening in the seat and prompted Rivera to announce he would run for Florida's 25th congressional district on February 25, 2010. On August 24, he won the Republican primary with 63% of the vote. On November 2, Rivera defeated Democratic nominee Joe Garcia 52%–43%.
