The former Blues doctor tied the knot with partner Jason De Carteret, a polar explorer, at St Patrick’s Church in Soho.
A number of former players attended the service, including ex-Chelsea goalkeeper Mark Schwarzer.
However, none of the current Blues players or coaching staff were present.
Gibraltar-born Carneiro, who is suing Chelsea manager Jose Mourinho for constructive dismissal, is currently without a job after leaving her post at Stamford Bridge.
Carneiro’s lawyers have failed to agree a settlement with Chelsea so far. The three-month period in which a claim must be notified ended on November 8.
An employment tribunal hearing is set to take place early next year and could be potentially embarrassing for the club, and for that reason such cases are usually settled beforehand.
The doctor was dropped from first-team duties on August 8 after she and physio John Fearn were criticised by manager Jose Mourinho for going on to the pitch to treat Eden Hazard – the player had to leave the field temporarily as a result meaning Chelsea were briefly down to nine men.
Mourinho has since been cleared by the Football Association of using discriminatory language towards Carneiro but the doctor has criticised the governing body over its investigation.
