Luis Vicente Gutiérrez (born December 10, 1953) is an American politician. He served as the U.S. representative for Illinois's 4th congressional district from 1993 to 2019. From 1986 until his election to Congress, he served as a member of the Chicago City Council representing the 26th ward. He is a member of the Democratic Party and was a member of the Congressional Progressive Caucus during his tenure in the House. In the 113th Congress, with his 20 years of service, Gutiérrez became, along with Bobby Rush, the longest serving member of the Illinois House delegation, and so was occasionally referred to as the unofficial "dean" of the delegation.

In 1998 he was caught up in a corruption scandal in which Gutierrez had only paid $274 dollars in property tax while his neighbors were paying up to $5,000. Gutierrez claimed his property was a vacant lot.

Of Puerto Rican descent, he is a current supporter of Puerto Rican independence, and the Vieques movement. Gutiérrez is also an outspoken advocate of workers' rights, LGBT rights, gender equality, and other liberal and progressive causes. In 2010, Frank Sharry of America's Voice, an immigration reform advocacy group, said of Gutiérrez: "He's as close as the Latino community has to a Martin Luther King figure." His supporters have given him the nickname El Gallito – the little fighting rooster – in reference to his fiery oratory and political prowess.

His district, the 4th congressional district, was featured by The Economist as one of the most strangely drawn and gerrymandered congressional districts in the country and has been nicknamed "earmuffs" due to its shape. It was created to pack two majority Hispanic parts of Chicago into one district, thereby creating a majority Hispanic district.

In November 2017, Gutiérrez announced that he would retire from Congress at the end of his current term, and not seek re-election in 2018. As of 2021, Gutiérrez lives in Puerto Rico.

Gutiérrez was born and raised in the Lincoln Park neighborhood of Chicago, then an immigrant and working-class community. His mother was an assembly-line worker, and his father was a cab driver. After his freshman year at St. Michael's High School, his parents moved the family to their hometown of San Sebastián, Puerto Rico. Gutiérrez, who had never before visited the island, reluctantly followed his parents; there, he learned to speak Spanish. Gutiérrez said of his experience moving from Chicago to Puerto Rico: "In Lincoln Park, I had been called a spic, then, all of a sudden, I land on the island and everyone calls me gringo and Americanito. I learned to speak Spanish well."

In 1974, Gutiérrez returned to Chicago and enrolled at Northeastern Illinois University. He got involved in student activism and social justice issues, writing for the student publication Que Ondee Sola and serving as the president of the Union for Puerto Rican Students. In 1976, while a senior at Northeastern Illinois, he began driving a cab in order to raise enough funds to visit his long-time girlfriend, Soraida, in Puerto Rico. In 1977, after graduating from Northeastern Illinois University with a degree in English, he returned to Puerto Rico and married Soraida. The couple returned to Chicago in 1978, and, unable to find other work, Gutiérrez took up taxi driving full-time. Gutiérrez eventually found work as a Chicago Public School teacher and later a child abuse caseworker with the Illinois Department of Children & Family Services.

In 1983, Gutiérrez left his job with the Illinois Department of Children and Family Services to run against incumbent Dan Rostenkowski for 32nd ward Democratic committeeman in the March 1984 primary election. To fund his campaign, Gutiérrez returned to driving a cab seven days a week, 14 hours a day. Gutiérrez's work as a taxi driver grew his campaign fund to $6,000, against which Rostenkowski had hundreds of thousands of dollars. Reporting on Gutiérrez's early political career, Jorge Casuso and Ben Joravsky of the Chicago Tribune wrote: "Gutiérrez thought he could win. Washington's 1983 victory – the first local race Gutiérrez had voted in – had left him wildly optimistic. Before that, he didn't think blacks, Hispanics and poor people could win a legitimate voice in local government."
