Arantza Urkaregi (born 23 April 1954) is a mathematician, union organizer, and feminist politician.

While these meetings fit into the broader theme of feminist movements in the 60s and 70s, they are especially important because of the particular anti-feminist pushback in Basque.

Overall, these meetings, which had attendance far exceeding expectations, were key in demonstrating the existence of, and support for, a Basque feminist movement.

[2] Urkaregi has also been deeply involved in a Basque teachers union (Steilas), which recently (in 2020) went on strike in protest of insufficient support for teaching in the midst of COVID-19.

[7] As demonstrated by Inguma, which is a database for publications in the Basque scientific community, Urkaregi has published extensively about biostatistics.
