Gregory John Barro, known as Greg Barro (born 1957), is an attorney in Shreveport, Louisiana, who served as a Democratic state senator from 1992 to 1996 for District 37 (Caddo and Bossier parishes) in the far northwestern portion of the state.
Barro is a son of the late Albert Barro, Sr. His paternal grandparents are the late Abe and Pauline Aura Barro. His brother is Albert Barro, Jr., also of Shreveport.
In 1987, Barro nearly unseated Republican State Representative Arthur W. "Art" Sour, Jr. (1924-2000) in House District 6. On November 16, 1991, Barro won his Senate seat in the same election in which the Democrat Edwin Edwards defeated former Ku Klux Klansman David Duke for governor. Duke ran as a Republcian without official party support. The incumbent Democratic state senator, Sydney B. Nelson, a Shreveport lawyer, did not seek a fourth term in 1991.
Barro defeated Republican Ronald Bradford "Ron" Fayard (1946–2011), a 1964 graduate of Bossier High School and  a real estate agent from Bossier City, 59-41 percent. In 1995, Barro ran a strong third in the nonpartisan blanket primary but lost a general election berth to another Democrat, Melissa Flournoy, a state representative who was in turn handily defeated by the Republican Max T. Malone of Shreveport.
Barro graduated from Captain Shreve High School, where one of his classmates was future Shreveport Mayor Keith Hightower. Barro received his Bachelor of Arts degree from Louisiana State University in Baton Rouge, and procured his legal degree from the LSU Paul M. Hebert Law Center. He is Roman Catholic.
