Thomas Aquinas Foran (January 11, 1924 – August 6, 2000)[1] was a United States Attorney best known as the chief prosecutor in the Chicago Seven conspiracy trial in which seven defendants, including Jerry Rubin, Abbie Hoffman, David Dellinger, Rennie Davis, and Tom Hayden, were charged with inciting riots at the 1968 Democratic National Convention.

[6][7] In private practice, he established a reputation as an expert in eminent domain law, representing the city of Chicago in major public works projects, but he also acted as counsel for property owners.

[8] While in this role, he successfully prosecuted more than 150 organized crime figures, including Felix Alderisio, Jackie Cerone, Fiore Buccieri, Richard Cain and William Daddano.

In 1969, he was the chief prosecutor of the Chicago Seven conspiracy trial which charged seven defendants, including Jerry Rubin, Abbie Hoffman, David Dellinger, Rennie Davis, and Tom Hayden, with inciting riots at the 1968 Democratic National Convention.

[1] He was later censured by a United States Court of Appeals for the Seventh Circuit panel "for their open hostility toward the defendants and their failure to fulfill 'the standards of our system of justice'".
