The Danish Foreign Ministry said the parliament's Foreign Affairs Committee aborted the trip after the Iranian parliament demanded an apology because Danish newspapers reprinted the cartoon that caused outrage in Islamic countries two years ago.
Most Muslims consider depictions of the Prophet Mohammad offensive.
"The Iranian parliament had demanded an apology of the Danish parliamentary delegation, which they of course cannot accommodate," Foreign Minister Per Stig Moller said in a statement.
Police arrested two Tunisians and a Dane of Moroccan descent on Tuesday, accusing them of planning to kill a cartoonist who drew one of the images.
Fifteen Danish newspapers reprinted his drawing on Wednesday in protest against the alleged plot.
Dozens of Islamist students burned the Danish flag in southern Pakistan on Thursday, while in Kuwait, several parliamentarians called for a boycott of Danish goods.
Publication of the cartoons two years ago led to protests in Muslim countries around the world.
Moller said the committee refused to apologise.
Ten members of the committee had scheduled a four-day trip to Iran starting Feb. 18.
