Christiaan Anton Jansen (born 27 October 1966) is a Dutch politician for the right-wing populist Party for Freedom (PVV).

He has been serving as State Secretary for Public Transport and the Environment since July 2024, and he previously was a member of the House of Representatives between November 2019 and March 2021.

Simultaneously, he served a member of the States of Flevoland starting the next year, rising to the position of party leader of the province in 2013.

[17] At the start of 2016, he called Mayor Franc Weerwind a "wally" (flapdrol) on Twitter after he had decided to not prohibit a meeting that included two controversial Islamic preachers.

[20] Another reason for this was that Jansen had incorrectly suggested the year before that a former alderman was pressured by civil servants not to cooperate in an audit office investigation.

[25] During the formation of the executive board of the North Holland city Den Helder, Jansen was proposed as finance alderman.

[33] Jansen became the PVV's party leader in the States in June 2013, after his predecessor Joram van Klaveren resigned because he could no longer combine the position with his membership of the House of Representatives.

[38] When the Van Geel Commission came out with its advice about the surplus of large herbivores in the nature reserve Oostvaardersplassen later in 2018, Jansen opposed the proposed shooting of animals and instead advocated using birth control to decrease the population.

It was carried by a narrow majority, and the Central Agency for the Reception of Asylum Seekers (COA) halted its plans days later.

[50] The PVV became part of the coalition alongside the BBB, VVD, Christian Union, and SGP, and Jansen vacated his seat to become a Deputy for Economic Affairs and Higher Education in the provincial executive on 29 June 2023.

[51][52][53] When asked in the confirmation hearing about earlier ant-Islamist statements, Jansen replied he would not distance himself from them but promised to stop making them as a deputy.

[31] His party won twenty seats and he personally received 382 preferential votes, the majority of which came from his home province of Flevoland.

[56] In October 2019, MP Sietse Fritsma stepped down to start a business, resulting in Jansen becoming a member of the House of Representatives.

He pointed at the fact that other European countries had taken more action and said Minister for Medical Care Bruno Bruins should think ahead instead of solely listening to experts.

[63] After the PVV, VVD, NSC, and BBB formed the Schoof cabinet, Jansen was sworn in as State Secretary for Public Transport and the Environment on 2 July 2024.

[66] When asked in a Goedemorgen Nederland [nl] interview, Jansen stated that he still supported Wilders's 2014 speech about wanting fewer Moroccan people.

However, he distanced himself from his response shortly after, clarifying that it reflected his personal opinion rather than that of the cabinet, following a rebuke from Prime Minister Dick Schoof.

The coalition agreement contained a commitment to postponing their implementation, and a motion by Hester Veltman (VVD) was passed by the House in October 2024 calling on Jansen to exempt commercial vehicles until 2029.

[68][69] In accordance with a ruling by the OSPAR Commission, Jansen classified PFAS as a substance of very high concern, requiring companies to take steps to release these chemical compounds into the environment.

[7] During his political career, he has also opposed Islamization and the construction of new mosques in Almere, and he has said he would like the government to revoke passports of criminal immigrants with multiple citizenship.
