Murray, widely regarded as one of Britain's all-time great sportsmen, won Olympic singles gold in 2012 and 2016, apart from capturing three Grand Slam titles in a glittering career.
"Arrived in Paris for my last ever tennis tournament @Olympics. Competing for Great Britain have been by far the most memorable weeks of my career and I'm extremely proud to get do it one final time," the 37-year-old wrote on social media.
The injury-plagued player bid an emotional farewell at this year's Wimbledon, the venue where he won two major titles, following a doubles defeat partnering his brother Jamie.
Murray, who underwent surgery on June 22nd to remove a spinal cyst which was compressing his nerves and made him lose control and power in his right leg, had decided he was not fit enough for the demands of singles competition at the All England Club.
The tennis competition at the Olympics begins on July 27th and Murray will be playing both singles and doubles.
Murray resurrected his career after having hip-resurfacing surgery in 2019 but has since struggled to make the latter stages of leading tournaments.
