Häststam is a Swedish horse pedigree database that has documented horses and their ancestry since 2006. Founded by Karin Halvarsson and built by horse enthusiasts, the site serves people interested in horses, breeds and genealogy. Its searchable archive lists more than 711,000 horses across 301 breeds, with information on known ancestry, breeders and stallions, as well as photographs for many entries.

Visitors can search for individual horses, explore breed profiles and studbooks, and use advanced search tools to find records. The site also highlights popular breeds and frequently viewed horses, and provides lists of commonly recorded sires and dams. Users can submit horse information and upload photographs, helping expand the shared archive. Recent image uploads showcase horses from a range of breeds and backgrounds.

Häststam presents itself as a community-built resource for exploring equine family histories. Alongside its database, it offers links and information about the site, including contact details and publishing and privacy policies. Its broad collection and contribution options make it a practical destination for researching horse pedigrees.
