Frederik Jan Harm "Freek" Jansen (born 6 December 1992) is a Dutch politician who served as a member of the House of Representatives (2021–2024) for the far-right Forum for Democracy (FvD) party.

Reports about extremist messages by members of the youth wing in 2020 led to criticism of Jansen and caused a split within FvD.

[9][1] When Forum for Democracy received a plurality of the votes in the 2019 provincial elections, Jansen co-wrote Baudet's victory speech.

[7] Besides, news magazine HP/De Tijd reported that his former superior at the Westland local council had written in a statement of defense for a labor dispute that Jansen had downplayed the Holocaust and had lauded the economic policies of Nazi Germany.

[12] In April 2020, HP/De Tijd published an article about members of Forum for Democracy's youth wing being worried about right-wing extremist ideas that were expressed in WhatsApp group chats.

[15] Newspaper Het Parool wrote the following month that antisemitic, Nazi, and homophobic thoughts were still being held and expressed by members of the FvD's youth wing.

[2][23] Jansen stayed on as chair of the Forum for Democracy youth wing until September 2021, and he joined FvD's board as treasurer in November.

[27] Jansen was reprimanded in October 2022 by the House of Representatives for refusing to disclose his position as board member of publisher Amsterdam Media Group, while Baudet was suspended.

[28] The House's integrity body advised the following year to suspend Jansen along with Baudet and Van Meijeren for one week for omitting roles at a meal-kit delivery service on their disclosure forms.

[29] In early 2022, Jansen declined a seat in the States of Overijssel, which was offered to him as there was a vacancy and he had been FvD's lijstduwer in the 2019 provincial elections.

Jansen said that without them the Netherlands would not be suffering from crime, street disturbances, a housing shortage, and overcrowded classrooms and hospitals (the latter during the COVID-19 pandemic).
