Hjälmarsrör (Swedish: Hjelmarsrör Ganggrift; also known as Hjelmrör, Vetterlingsgården, or Falköping 3:1) is a passage grave with an 18-sectioned division located on Wetterlinsgatan Street on a hill in the industrial area of Falköping in Falbygden, Västergötland, Sweden. According to Karl Esaias Sahlström (1884–1964), it is considered one of the oldest in the country. The passage grave is a type of construction from the late Neolithic period, consisting of a chamber and a structurally separated, lateral passage. This form is primarily found in Denmark, Germany, and Scandinavia, with occasional occurrences in France and the Netherlands.
