Mateen was responsible for the shooting rampage at Pulse nightclub in Orlando on June 12, 2016, which left 49 people dead. He pledged allegiance to the Islamic State group during a standoff with police.
Salman was booked into Santa Rita Jail in Almeda County in California. She is expected to face a judge in Oakland on Tuesday morning.
Last year, Salman told The New York Times that she was aware her husband watched Jihadist videos, but she didn't think much of it because he had been cleared by the FBI.
WFTV legal analyst Bill Sheaffer said in a 2016 interview about Salman that "in order to successfully prosecute the wife, they're going to have to show she did something in furtherance of that crime."
"I hope today's news provides some comfort to the families who are mourning their loved ones," Florida Gov. Rick Scott said in a statement.
