Nuestros Ranchos is an online genealogy group and research community focused on family lineages connected to the Mexican states of Jalisco, Zacatecas, and Aguascalientes. Founded in 2003, the organization brings together people who are actively researching regional history and ancestry, with a stated emphasis on serious genealogical work. Its website supports members and visitors through discussion forums, albums, files, links, films, and a regional map.

Members use these features to share research, ask for help interpreting historical records, exchange documents and family information, and discuss ancestors, archival sources, and local history. The site includes both English- and Spanish-language content and welcomes contributions ranging from document-reading questions to detailed investigations of family lines. Nuestros Ranchos describes its online community as popular and high-traffic, sustained by the participation and knowledge-sharing of its members.

According to a site administrator, it operates without advertisements or monthly user fees. The group also provides membership requirements for prospective registrants, reflecting its focus on a dedicated genealogical community rather than a general-purpose social network
