Anthony, who is Company magazine's ad director, takes over next month from Jane Candlish, who is moving to Taiwan with her partner after a year in the role.
Having originally joined Natmags in 1994 as a junior classified sales executive, Anthony rose through the company to become ad director for Company magazine. Between 2003 and 2005 she oversaw the biggest growth in ad revenues in the magazine's 28-year history.
Jan Adcock, Cosmopolitan group publishing director, said: "Ceri brings with her a fantastic breadth of skills and knowledge of the young women's market."
The Cosmopolitan group consists of Cosmopolitan, CosmoGirl! and Cosmopolitan Hair and Beauty.
