Stephen Jean-Marie Pichon (10 August 1857 – 18 September 1933, Vers-en-Montagne) was a French journalist, diplomat and politician of the Third Republic.

He served as French Minister to China (1897–1900), including the period of the Boxer Uprising.

[1] Stephen Pichon was appointed Resident-General of the Tunisian Protectorate in 1901, replacing Georges Benoit.

Stephen Pichon in Paris managed the French agreement with transformation of Czechoslovak National Council to the Provisional Czechoslovak government on 26 September 1918 (when Edvard Beneš received confirmation of Tomáš Garrigue Masaryk from Washington).

[3] His most notable service was under Clemenceau during the latter part of the First World War and the Paris Peace Conference of 1919, but, like most of the other foreign ministers at the conference, Pichon was largely sidelined by the more forceful figure of his head of government.
