Duraid Abdulrahman, 30, of Manchester Road, pleaded not guilty to the charge when he appeared at Swindon Crown Court in March.
Last week, Abdulrahman was sentenced to seven years in prison following a four day trial.
Abdulrahman raped his victim, a vulnerable 38-year-old woman, multiple times on Sunday 7 December 2014 at a residential address in Swindon.
Detective Constable Matt Lewis, of Swindon CID, said: “Duraid Abdulrahman showed no remorse for his actions by pleading not guilty to the offence, forcing his victim to endure a trial at court and relive the terrifying experience she was put through at the hands of Abdulrahman. His actions will have a long lasting effect on his victim.
“I am pleased with the sentence given out at court and I am hopeful that it will encourage other victims of sexual assault to find the strength to come forward and report offences – justice will be done.
“I would like to take this opportunity to praise the bravery of the victim in coming forward and reporting this incident and thank the ISIS Women’s Centre in Swindon who we worked in close partnership with to ensure this case was brought to court successfully.
“Anyone wishing to report a crime should contact Wiltshire Police on 101 or Crimestoppers on 0800 555 111 where information can be left anonymously.”
