Alain Émile Louis Marie Poher (French: [alɛ̃ pɔɛʁ]; 17 April 1909 – 9 December 1996) was a French centrist politician, affiliated first with the Popular Republican Movement and later with the Democratic Centre. He served as a Senator for Val-de-Marne from 1946 to 1995. He was President of the Senate from 3 October 1968 to 1 October 1992 and, in that capacity, served twice as the country's interim president. Candidate in the 1969 presidential election, he was defeated by Georges Pompidou in the second round.

Poher was born in Ablon-sur-Seine, Val-de-Marne.

He graduated from the Lycée Louis-le-Grand and the Lycée Saint-Louis in Paris and later studied law. On 19 August 1938 he married Henriette Tugler, with whom he had one daughter, Marie-Agnès.

His political career began in 1938, when he became a junior executive officer in the Ministry of Finance.

Later he served on several positions before entering Senate:

A longtime ally and political protege of Schumann, Poher was elected to the Senate in 1952, where he remained for over 40 years (until 1995). As Senator he continued to serve in some governments and his home town mayor. Like Schuman, he was known for strongly pro-European integration positions, having served as President of the European Parliament (1968–1969).
