Philip Michel Frans "Filip" Dewinter (born 11 September 1962) is a Belgian politician, journalist and commentator. He is one of the leading members of Vlaams Belang, a right-wing Flemish nationalist and secessionist political party.

Dewinter's grandfather on his mother's side was a resistance fighter who had been very active in the resistance group, the Witte Brigade (White Brigade), in Blankenberge.

In 1983, he became a member of Vlaams Blok. In November 1987, he was elected member of the Belgian parliament, in which he formed a political faction with Gerolf Annemans (who, earlier that year, had succeeded to founder-Flemish Block president Karel Dillen). Under Dewinter's leadership, the parliamentary group continued to grow, notably in 1991, when the Flemish Block, from a small party, grew to about 12% of the voters.

In 2010, he participated in a conference in Israel organised by Likud on the fight against terrorism.

An extreme right-wing activist is sentenced to five years in prison in 2014 for planning the murder of Filip Dewinter, hoping to drag Belgium into civil war.

In October 2022, Dewinter was physically assaulted by a left-wing activist while giving a talk at a community centre in Kessel-Lo. The incident was condemned by CD&V chairman Sammy Mahdi, MR chairman Georges-Louis Bouchez, and Flemish minister Zuhal Demir of the N-VA.

On March 25, 2024, an investigation by Humo magazine and the Apache website revealed that Filip Dewinter had worked for several years as a "senior political advisor" for China.

One month later it was revealed that Filip Dewinter was also involved in the then uncovered Russian Influential Network "Voice of Europe".
