Agustín Pedro Justo Rolón (26 February 1876 – 11 January 1943) was an Argentine military officer, diplomat and politician, who served as the president of Argentina from 1932 to 1938 during the Infamous Decade. Justo took part in the coup of 1930, becoming president two years later thanks to widespread electoral fraud. His presidency was part of the period known as the Infamous Decade, which lasted from 1930 until 1943. He established the country's central bank and introduced a nationwide income tax.

Roca Jr. had signed the Roca-Runciman Treaty. His name was mentioned as a candidate a new period during the unsteady government of Ramón Castillo, but his early death at 66 thwarted his plans.
