Actress Shailene Woodley is to stand trial in North Dakota early next year on charges related to her protest against the Dakota Access pipeline.
Shailene, 24, was among 27 activists arrested on October 10.
The Divergent and The Fault In Our Stars star, who live-streamed her arrest on Facebook, pleaded not guilty last week to criminal trespass and engaging in a riot.
Court documents show the Hollywood star's trial is scheduled January 25 in state court in Mandan.
She could face two months in jail and $3,000 (£2,454) in fines if convicted of the two misdemeanours.
The Standing Rock Sioux want construction of the $3.8 billion (£3.1 billion) pipeline halted, saying it could taint water supplies and encroach on tribal burial sites.
Protests supporting the tribe have been going on for months, with 269 people arrested as of Sunday.
