Beraintsi (Bulgarian: Бераинци, pronounced [bɛˈraint͡si]) is a small village in Tran Obshtina, Pernik Oblast.

It stems from a family name itself derived from the personal name Beraya, a vocative form of Beray.

The first school in the Znepole (approximately today's Tran municipality) was opened in 1778 by Trichko Gusin and existed for nearly a century.

Many years ago, there was a large stone in the Pobit Kamak area, which was broken at the place where the border with Serbia was supposed to be, but one of the locals managed to move the place of the stone to the village of Strezimirovtsi during the night.

There are traces of a prehistoric settlement - in the Zavoy locality, on the right bank of the Erma River, on an area of about 10 decares.

It was a small one-nave church, similar to those of the late Middle Ages in the Gornostrum and Znepol lands.
