Pag Triangle (Croatian: Paški trokut) is a land formation in the shape of an isosceles triangle located near Novalja, a small town on the Croatian island Pag. The triangle has one side measuring approximately 32 metres (105 ft) and two sides both measuring 22 metres (72 ft). It differs from the surrounding area in the fact that the rocks inside the triangle are of different structure than rocks outside the triangle. Croatian Ufologist Stjepan Zvonarić believes it was the site of a UFO landing which heated the rocks to extreme temperatures in the past. This property is unique to the Pag Triangle rocks, and is not found in rocks in the surrounding area.
Since its discovery in 1999, it is estimated that the Pag Triangle has been visited by over 500,000 tourists. It is a protected area of the Town of Novalja. Croatian ufologists have linked the existence of the triangle to a series of UFO sightings in late 20th century over the island of Pag, while some perceive the triangle as a sign of Holy Trinity, sometimes associated with Catholic priest Zlatko Sudac receiving his stigmata during a conversation about the triangle. In early 2009, a road was built connecting the triangle to the nearby village Caska and thus making it more accessible to visitors.
