The Society of Genealogists (SoG) is a UK-based educational charity, founded in 1911[2] to "promote, encourage and foster the study, science and knowledge of genealogy".

[4] After Charterhouse Buildings was sold in 2020,[5] in December 2023, after a period in temporary accommodation, the Society opened new premises in Islington, just off the City Road.

[6] The Society possesses the largest family history research library in the United Kingdom, accessible to all members without charge and available to be used by the general public on payment of a fee.

This material is now hosted commercially by Findmypast with a separate free service to members run by the Society itself on its own web site using the Frontis Archive Publishing System.

The society runs a programme of lectures, visits, and courses every year, and publishes textbooks, indexes, and a quarterly journal, Genealogists' Magazine.
