Eva Martinez Guzman (born January 12, 1961) is an American attorney, politician, and jurist who served as a member of the Texas Supreme Court from 2009 to 2021.

Guzman was initially appointed to the court by then-Governor Rick Perry in 2009 to fill the seat vacated by Justice Scott Brister, who had resigned with more than a year left in his term.

[6] At the time of her appointment to the supreme court, then-Governor Perry called Guzman a "principled conservative with an "unmatched work ethic".

In her June 7, 2021 resignation letter to Governor Greg Abbott, Guzman expressed gratitude for the opportunity to serve the people of Texas and highlighted her work on two supreme court commissions devoted to children in the legal system and access to justice for Texans of limited means.

[12] Guzman's announcement meant that the current incumbent, Ken Paxton, who is embroiled in multiple civil and criminal controversies, acquired a second high-profile challenger from within his own party.

[17] In 2021, Guzman joined Chamberlain Hrdlicka as a shareholder, serving in the commercial litigation and appellate practices in the Houston and San Antonio Offices.

A resident of Cypress in Harris County, Guzman is the first Hispanic woman to serve on the Texas high court for civil appeals.
