Sara Cato (Selma) Meyer (also Meijer) (Amsterdam, 6 July 1890 – Berlin, 11 February 1941) was a Dutch pacifist, feminist[1] and resistance fighter.

In the 1930s, Meyer served on various committees, among which were ones for the assistance and relief of young German refugees and for victims of the Spanish Civil War.

She was one of the founders of the National Peace Centre (NVC) on 13 August 1936 and in January 1937, with CPN chairman Ko Beuzemaker and railway unionist Nathan Nathans, she attended an International Conference for Aid to Republican Spain, which was held in Paris.

In addition, she was in charge of the Holland Typing Office, which only employed women and which played an important part in the publication of Kameradschaft, a magazine by Ebeling and Theo Hespers.

In April 1940, Meyer became ill. By the time the German troops invaded the Netherlands on 10 May 1940, she had travelled to Zeeland to recover.
