The Chasovennye people (also known as the Semeyskie or Semeiskie people east of Lake Baikal) are a Siberian sect of the Old Believers, Eastern Orthodox Christians who reject the reforms of Patriarch Nikon of Moscow in the 1650s and retain pre-Nikonian religious practices. Although they once allowed priesthood, they eventually joined other priestless (Bezpopovtsy) movements and outlawed priesthood and sacraments beyond baptism. The term Chasovennye itself refers to the literal chapels in which liturgical practices such as baptism occurred.
