Franklin Delano Roosevelt III (born July 19, 1938) is a retired American economist and academic. Through his father, he is a grandson of President Franklin D. Roosevelt and Eleanor Roosevelt, and through his mother he is a member of the prominent du Pont family.
Roosevelt was the first child born to Franklin Delano Roosevelt Jr. and his first wife, Ethel du Pont. He was born during his paternal grandfather Franklin D. Roosevelt's second term as president and was his eighth grandchild to be born. After his birth, his father said, "'Battling' Frank III is a beautiful baby." 
He has a younger brother, Christopher du Pont Roosevelt, born 1941, also from his parents' marriage. From his father's later marriages (he married 5 times in total), he has two younger half-sisters, Nancy Suzanne Roosevelt (born 1952) and Laura Delano Roosevelt (born 1959), and a younger half-brother, John Alexander Roosevelt (born 1977). He also had a younger half-brother, Benjamin S. Warren III (born 1954), from his mother's later marriage to attorney Benjamin S. Warren, Jr. 
After graduating from St. Mark's School in Southborough, Massachusetts, Frank Roosevelt received his Bachelor of Arts in Economics from Yale University in 1961, his master's degree from Columbia University in 1968, and his Ph.D. from The New School. 
His dissertation was entitled Towards a Marxist Critique of the Cambridge School. His work primarily focused on combining Marxism and capitalism in an attempt to make modern economic systems more "fair" and less prone to the "winner takes all" scenario.
In 1977, he became a professor at Sarah Lawrence College in Yonkers, New York, where he was chair of the social sciences faculty from 1988 to 1990 and from 1991 to 1993.  In retirement, he continued to speak out on his grandparents' legacies.  
He refers to himself as a "radical" or "alternative" economist. 
Rhona Free, one of his former students who is a professor of economics at Eastern Connecticut State University, was named in 2004 one of four U.S. Professors of the Year by the Carnegie Foundation for the Advancement of Teaching and the Council for Advancement and Support of Education. In her acceptance speech, she cited Roosevelt as a significant influence, saying, "The most important teacher I ever had was Frank Roosevelt, an economics professor at Sarah Lawrence. He's much more interested in teaching than in testing and in encouraging than in evaluating. In his classes even an average student, as I was, can learn to think critically, express thoughts carefully, and view the world with an open mind." 
In 2004, the university awarded him the Lipkin Family Prize for Inspirational Teaching. 
Roosevelt, who lives in Manhattan, was a member of the Board of Trustees of the Manhattan Country School.  from 1970 to 2010. In 1981, he led the effort to put the school's tuition system on a sliding scale.
Roosevelt has written in support of market socialism.
He married Grace Rumsey Goodyear on June 18, 1962.  She is the daughter of Austin Goodyear and Louisa Robins (granddaughter of Thomas Robins, Jr. and Winifred Hamilton Tucker). They have three children, including a set of twins:
- Phoebe Louisa Roosevelt (born February 25, 1965)
- Nicholas Martin Roosevelt (born June 8, 1966, twin)
- Amelia "Amie" Roosevelt (born June 8, 1966, twin), a concert violinist
