State Police spokesman Stephen Jones says three men were seen near the 8-by-4-foot wooden cross, which was set ablaze off Route 9 around 8 p.m. Wednesday night.
Jones says troopers patrolling the area stopped the men to question them.
Jones says Nicholas Comis, 22, of Tuckerton appeared to have gas stains on his pants and was arrested Wednesday night. The other two men, Daniel Enders, 22, of New Gretna, and Christopher Hurrll, 21, were arrested Thursday.
All three are charged with bias intimidation and conspiracy to commit arson. The charges carry a three- to five-year sentence upon conviction.
Jones says there is no known target of the cross burning.
It's wasn't clear Thursday if the men had attorneys. No telephone listings for them could be located.
