Ebba Thomsen (3 May 1887–18 December 1973) was a Danish actress during the golden era of silent films in Denmark. Thomsen was best known for her roles as the elegant leading lady opposite the Danish matinee idol Valdemar Psilander.
Ebba Thomsen was born in Copenhagen, Denmark on 3 May 1887, the daughter of Ove Thomsen, one of the leading Danish fashion designers. Thomsen debuted on stage at Det Ny Teater in 1910 and began to perform in cinema in 1912 at Nordisk Film. From then until the early 1920s, Thomsen appeared in about 75 films—mostly as the lead actress—and achieved star status in Denmark. Her most notables roles were in films in which she worked with Nordisk Film's biggest male star, Valdemar Psilander.
In a newspaper interview for her 50th birthday, Thomsen said that her "unique success depended on two things: First, that Psilander and I suited one another. I was actually a little too tall for him, yet our types suited each other, our movements, our acting. In short, we were a born 'film-couple'." Thomsen then credited her father with giving her "an absolute sense of style. I knew precisely how every fabric should look on me, whether it was a princess' gown or a washerwoman's rags." Thomsen was usually cast in roles as princesses, countesses, or artists.
