Baron Péter Apor de Altorja (1676–1752) was a Hungarian count (főispán) and historian.
He started his studies in 1686 in Kolozsvár after he continued it in Nagyszombat Hungarian Catholic University.
In 1713, he was granted the countship (as hereditary count, part of the aristocracy, only title).
He fled from the epidemic to the Moldavian Galați and spent few years there.
In 1744, he was nominated to government position in Vienna as "main court consultant" and received from King Charles III a golden necklace.
