Judge William Sessions said Ozturk, a Ph.D student at Tufts University in Massachusetts, should be released "immediately" from custody while her removal proceedings continue.
The State Department revoked Ozturk's student visa after she co-authored an article in the university newspaper, The Tufts Daily, criticizing the college's handling of student anger over Israel's genocidal war on Gaza.
Video of the 30-year-old Ozturk's March 25 arrest by masked agents on a sidewalk sparked outrage online, and added to concerns about freedom of speech and respect for due process under Trump.
Sessions echoed the concerns during Friday's live-streamed custody hearing, at which Ozturk appeared remotely from a detention center in Louisiana.
"Continued detention potentially chills the speech of the millions and millions of individuals in this country who are not citizens," the judge said.
"Any one of them may now avoid exercising their First Amendment rights for fear of being whisked away to a detention center from their home," he said.
"Her continued detention cannot stand," Sessions said. "The court orders the government to release Miss Ozturk from custody immediately."
The judge said he was not putting any travel restrictions on Ozturk and she was free to return to her home in Massachusetts.
Ozturk is one of a number of foreign students facing deportation over their pro-Palestinian campus activities, and she still faces removal proceedings.
The decision to release her from custody was welcomed by Turkey but condemned by the White House.
Turkish Justice Minister Yilmaz Tunc, in a post on X, called it a "positive development" and said it was "unacceptable for someone to be prosecuted because of their faith or their support for Palestine."
Stephen Miller, a senior White House official, lashed out at the decision, saying "there's a judicial coup in this country."
"Foreigners in this country do not have a right to stay in this country if they support designated terrorist organizations like Hamas," Miller told reporters, distorting another call for a ceasefire in the war-battered territory.
"The secretary of state has the absolute authority... to revoke an immigration benefit or a visa and then to pursue a deportation," he added.
'Won't stop fighting'
Tufts University has publicly backed Ozturk, demanding her release so she can return to the school and complete her doctoral studies in child development.
Jessie Rossman, legal director at the American Civil Liberties Union of Massachusetts, which is among the groups representing Ozturk, welcomed her release.
"For 45 days, Rumeysa has been detained in Louisiana," Rossman said. "During that time, she has suffered regular and escalating asthma attacks.
"And at the same time, the government has failed to produce any justification for her detention," Rossman said, adding that the ACLU "won't stop fighting until she is free for good."
Trump has targeted prestigious universities that became the epicenter of the US student protest movement sparked by Israel's war on Gaza, stripping federal funds and directing immigration officers to deport foreign student demonstrators.
Many fear that the campaign amounts to retribution and will have a chilling effect on free speech.
