Charles Joseph Margiotti (April 9, 1891 – August 25, 1956) was a nationally prominent[1] Pennsylvania lawyer who twice served as state attorney general.

[3] Margiotti himself was accused of arranging excessive tax collection fees for his own law firm and sued The Philadelphia Inquirer for libel over their coverage.

[5] In September 1948, Margiotti joined former CIO general counsel Lee Pressman in testing the campaign-expenditures provision of the Taft-Hartley Act.

Pressman and Margiotti each received $37,500 for their services – a fee CIO President Philip Murray called "outrageous, even for Standard Oil".

[1][8] Margiotti successfully defended Senator James J. Davis, who had been accused of running a lottery by mail on behalf of the Loyal Order of Moose.
