Russian Dolls: Sex Trade (Dutch: Matroesjka's, meaning Matryoshka doll, also known as Matrioshki or Matrёshki) is a Flemish drama series about a group of women from Lithuania and Russia who are taken to Belgium by a gang involved in the sex trade to work as sex slaves. The series starts in Lithuania, where the girls are chosen and where they have to sign a contract in Greek, which they cannot understand. The gang, under the lead of Ray Van Mechelen, takes the girls to Cyprus and from there they are taken to Club 69 in Belgium to work. Russian Dolls is sponsored by the Flemish Audiovisual Fund (Vlaams Audiovisueel Fonds).

Russian Dolls is produced and directed by Guy Goossens and Marc Punt.

Because of explicit scenes of sex and violence, the program is not appropriate for people under 16 years of age (according to Dutch and Belgian ratings).
