Roderick John Thomas (born 11 January 1947) is a Welsh former professional footballer who represented Wales at international level.
Swindon Town manager Bert Head brought Thomas to the County Ground from non-league Gloucester City in July 1964 – paying £500 for his services.
The following season saw Thomas establish himself as the club's first choice right back, and he also achieved his first international honours, being selected for the Welsh under-23 squad.
By the time he left in 1973, he had made the most international appearances ever by a Swindon player, having played in thirty matches for Wales.
He made another twenty appearances for his country, and had brief spells at Newport County, Bath City and Barry Town, before his retirement in 1982.
