The Paris Peace Conference gathered over 30 nations at the Quai d'Orsay in Paris, France, to shape the future after World War I. The Russian SFSR was not invited to attend, having already concluded a peace treaty with the Central Powers in the spring of 1918. The Central Powers - Austria-Hungary, Germany, Bulgaria and the Ottoman Empire - were not allowed to attend the conference until after the details of all the peace treaties had been elaborated and agreed upon. The main result of the conference was the Treaty of Versailles with Germany.

This list shows all nations and delegations who signed the Treaty of Versailles. All plenipotentiaries signed the treaty, except where indicated otherwise.^[1]

Brazil	João Pandiá Calógeras [pt] Rodrigo Otávio de Langgaard Menezes [es]
Canada	Robert Borden[lower-alpha 1] Charles Doherty Arthur Sifton	Signed under 'British Empire'. Prime Minister Borden fought successfully for Canada to have its own seat at the Conference, which the British and Americans eventually relented too, opening the doors to allowing Australia, New Zealand, Newfoundland, and South Africa to send representatives as well. Borden also insisted that he be included among those leaders to sign the Treaty of Versailles; however, it was agreed that Canada would sign under the British Empire.
China	Lu Zhengxiang[lower-alpha 1] Wellington Koo[lower-alpha 1] Cao Rulin[lower-alpha 1]	Many in China felt betrayed as the German territory in China was handed to Japan. Wellington Koo refused to sign the treaty and the Chinese delegation was the only nation that did not sign the Treaty of Versailles at the signing ceremony. At the time of the Paris Peace Conference there were two governments claiming to be the legitimate government of China: the Beiyang Government in Beijing, and Dr Sun Yat-sen's Guangzhou based Kuomintang (KMT) movement. However, they worked together to create the united diplomatic team that would plead China's case in Paris.

An oft-stated myth is that the Principality of Andorra was not invited to attend, due to an 'oversight' and that the issue of Andorra being at war was eventually resolved on September 24, 1958, when a peace treaty was signed. This claim first appeared in North American newspapers in 1958^[30][31] and has been repeated since.^[32][33] In reality, Andorra did not officially participate in World War I.^[34] In 2014, the news outlet Ràdio i Televisió d'Andorra investigated the 1958 claim and could find no documentation of any original declaration of war. Historian Pere Cavero could only find an exchange of letters between the German consul in Marseille and the Catalan Ombudsman, where the former asks if there is a state of war with Andorra and the latter responds they could find nothing in their archive to indicate this.^[35]
