Iaat (Arabic: إيعات also transliterated as Ya'ad, Yaad, Yaat, or Iaad) is a town and municipality located approximately 5 kilometers northwest of Baalbek, in the Beqaa Valley of Lebanon.

Ottoman tax registers between 1533 and 1548 indicate the village had 180 households and 4 bachelors, all Muslims.

[1] In 1838, Eli Smith noted Ei'at as a Metawileh village in the Baalbek District.

The column is believed in local legend to be related to Helena, mother of Constantine I.

[4][5] The British scholar George F. Taylor classified it among a group of temples of the Beqaa Valley and noticed that the position of the Iaat column was equidistant between the temples of Baalbek and Qasr el Banat.
