Janneke Marlene "Marja" van Bijsterveldt-Vliegenthart (born 27 June 1961) is a Dutch politician of the Christian Democratic Appeal (CDA).

Van Bijsterveldt disagreed with the way the other aldermen of the social-democratic PvdA and the liberal VVD had dealt with the matter, and following a motion of no-confidence she resigned.

In August 2009 she made a speech in the States General about Laura Dekker, a thirteen-year-old Dutch citizen whose plans to circumnavigate the world solo caused international controversy.

Van Bijsterveldt spoke against Dekker and agreed with the decision to make her a ward of court.

[1] In her recent interview with De Telegraaf, she added: ‘I am concerned about the excessive individualization in the Netherlands’, one of her next tasks before she get retired.
