Veresvatnet or Veressjøen is a lake in the municipality of Verdal in Trøndelag county, Norway. The lake lies in the eastern part of the municipality, just west of the border with Sweden and just south of Blåfjella–Skjækerfjella National Park. The 6.5 km2 lake sits at an elevation of 360 m above sea level, and it is considered to be one of the headwaters of the Verdalselva river since the lake's water flows out into the river Helgåa which later joins the Verdalselva. The village of Vera and the Vera Chapel lie on the northern shores of the lake.
