Annika Billström (born 7 April 1956) is a Swedish social democratic politician.

[1][2] Billström's background was as the chief financial officer of Handels, the Swedish Commercial Employees' Union between 1987 and 1994.

The congestion tax was decided on a municipality-level to ensure support by the Green Party for the newly formed Social democratic cabinet and Billström was forced to honor this agreement even though she had promised not to in the run up to the 2002 election.

In 2006 a referendum was held to let the people of Stockholm determine whether they wanted the entry tolls permanented or not, with more than 51% voting yes.

Billström's other decision was to turn a central building in Stockholm (Skatteskrapan på Södermalm) into student housing, which was criticised for being expensive for taxpayers.
