Eratigena duellica, the giant house spider, is a species of funnel weaver in the spider family Agelenidae. It is found in Canada, the United States, and Europe. The related species "Eratigena atrica" is also called the giant house spider.
"Eratigena atrica" was transferred from the genus "Tegenaria" in 2013. It was considered the same species as "Eratigena atrica" until 2018, when "Eratigena duellica", "Eratigena saeva", and "Eratigena atrica" were restored as separate species.
