The actress, who played Marissa Cooper in The OC for three years, was also booked for possession of illegal narcotics and driving without a valid licence.
She was believed to have been driving her white Range Rover in West Hollywood at around 3am when she was pulled over by police, who spotted her vehicle straddling two lanes of traffic. She was also alleged to have made a turn without signalling.
The Los Angeles County Sheriff's Department said they questioned Barton and found that she was under the influence of alcohol and did not possess a driver's licence.
She is currently being held in custody on $10,000 bail.
The 21-year-old recently revealed that she frequently felt frustrated while starring in The OC.
