The Gesta Hunnorum et Hungarorum[1] (Latin: "Deeds of the Huns and Hungarians") is a medieval chronicle written mainly by Simon of Kéza around 1282–1285.

The work is dated to 1282–1285 as it includes the Battle of Lake Hód (1282) but does not mention the Second Mongol invasion of Hungary in 1285.

He travelled widely in Italy, France and Germany and culled his epic and poetic materials from a broad range of readings.

By Kéza's own admission, he used contemporary German, Italian and French chronicles, but it has been proved that he freely used Hungarian sources also.

[2] The Gesta Hunnorum et Hungarorum was edited and translated in 1999 by László Veszprémy and Frank Schaer for the Central European University.
