Alain Émile Louis Marie Poher was a French politician who briefly served as Acting President of France twice, in 1969 and 1974. He held the office ad interim as President of the Senate following the resignation of Charles de Gaulle and the death of Georges Pompidou. Poher was affiliated with the Popular Republican Movement (MRP) until 1966 and later with the Democratic Centre (CD) and Centre of Social Democrats (CSD), which he joined in 1976.

The president of France, officially the president of the French Republic, is the executive head of state of France, and the commander-in-chief of the French Armed Forces. As the presidency is the supreme magistracy of the country, the position is the highest office in France. The powers, functions and duties of prior presidential offices, in addition to their relation with the prime minister and government of France, have over time differed with the various constitutional documents since the Second Republic.
