Gyula Illyés (2 November 1902 – 15 April 1983) was a Hungarian poet and novelist. He was one of the so-called népi ("from the people") writers, named so because they aimed to show – propelled by strong sociological interest and left-wing convictions – the disadvantageous conditions of their native land.
On 2 November 1956 he published his famous poem of the Hungarian revolution of 1956, which was not allowed to be republished in Hungary until 1986: "One sentence on tyranny" is a long poem written in 1950.
