Dorien Rookmaker (born 30 July 1964) is a Dutch politician of the More Direct Democracy (MDD) party, who served as a Member of the European Parliament between 2020 and 2024.

In March 2019, Rookmaker was on the electoral list in the Provincial Council elections on behalf of Forum voor Democratie (FVD) in both Gelderland and South Holland.

[3] Like Jeroen de Vries, she no longer felt comfortable with the "boreal bullshit" of FVD party leader Thierry Baudet.

In January 2024, she pleaded towards voters in NRC Handelsblad to ignore career politicians and look for individual candidates who she believes are "recognisable and authoritative",[10] with a view to the European Parliament elections in June the same year.

[2][6] During proceedings concerning the removal of the European Parliament's vice-president suspected of corruption, Eva Kaili from her post, Rookmaker abstained from voting in December 2022, along with two other MEPs.

[12] Rookmaker is in favour of a high-speed train between Amsterdam and Berlin, in fact also between all European capitals,[13] and made a Christmas greeting on that theme in December 2023.
