The village is located atop a nipple. For a long time it was called Nogaret the Fort because the church of Saint Stephen of Nogaret built in the center of the village, is surrounded by ditches that were filled in 1845. From there would come the name of Nogaret the Fort. There is a trace of the church which already existed in 1318. From 1538 to 1775 it was the annex of Saint-Martin de Montégut. It would seem that the village originated around the church and its cemetery. A few dwellings were then added to this first nucleus of population to form the small village of Nogaret.
The origin of the village could come from Guillaume de Nogaret who came to hunt, or from "Noyeraie", place planted with walnut trees.
On the coat of arms of Nogaret we find a walnut, the lion being the motto of John of Polastre Lord of Nogaret (1686).
The commune of Nogaret is located north of Montégut-Lauragais. It extends over different landscapes. The eastern part of the municipal territory is located in the plain of the Sor basin while the western part stretches on a series of plateaus in the basin of the Girou. The watershed is formed by the crest of the hills that run through the commune from North to South.
