Senator Jan Oberfalzer said Wilders will talk about freedom of speech and the "Islamization of Europe" on November 30, and show his 15-minute film, "Fitna."
The movie suggests Islam justifies violence and terror, and it prompted angry protests when it was released online last year.
Wilders, the leader of Holland's right-wing Freedom Party, was denied entry to Britain to show his film to legislators in February, but he returned on Oct. 16 after successfully suing the British government to overturn the ban.
Oberfalzer said in a statement that Wilders may say controversial things but they are "true in essence."
