The town of Avallon in Burgundy has honoured the Labour MP who was gunned down and then stabbed several times on June 2016 in the run-up to the Brexit referendum aged just 41.
A staunch believer in the European Union, Cox was killed in her constituency in West Yorkshire by Thomas Mair, labelled a "far-right terrorist" who was later sentenced to life imprisonment for her murder.
The translation of the sign on the French street named after her reads "Rue Jo Cox, British MP, murdered for her convictions, 22nd June 1974 to 16 June 2016."
France has traditionally honoured figures who have died by naming streets after them or in some cases train stations.
In receiving this honour, Cox joins esteemed company with former war-time Prime Minister Winston Churchill who has had several streets in France named after him.
One of these can be found in the southern Paris suburb of L'Haÿ-les-Roses.
Apart from politicians, British astronomer Edmond Halley, has had several streets named after him, including one in Montpellier.
One of the Paris Metro stops, George V was named after the British king to honour the UK's support of France during the First World War.
US Presidents George Washington, Woodrow Wilson, Franklin D. Roosevelt and John F. Kennedy have also received the honour. American civil rights campaigner Rosa Parks has also had an RER station named after her near Paris.
Cox's name is also on a list of people to be honoured with a street or square name in Brussels.
