Bramble was accused of groping one woman in a nightclub before assaulting another in a taxi on September 28.
The Ipswich-born player had denied the charges brought against him and, following a four-day trial, the jury found him not guilty at Teeside Crown Court.
Bramble was initially arrested after the taxi driver become concerned at the actions of the 30-year-old and subsequently drove him to the police station.
The former Newcastle and Wigan defender admitted that he was under the influence of alcohol, but claimed that he had shared a consensual kiss with the women in the taxi before her mood changed, and denied groping a separate woman in a nightclub that same evening.
Sunderland have refused to comment on the court ruling.
