Isidore Auguste Marie Louis Paulhan, was a French aviator. He is known for winning the first Daily Mail aviation prize for the first flight between London and Manchester in 1910.

Between 1906 and 1930, the Daily Mail newspaper, initially on the initiative of its proprietor, Alfred Harmsworth, 1st Viscount Northcliffe, awarded numerous prizes for achievements in aviation. The newspaper would stipulate the amount of a prize for the first aviators to perform a particular task in aviation or to the winner of an aviation race or event. The most famous prizes were the £1,000 for the first cross-channel flight awarded to Louis Blériot in 1909 and the £10,000 given in 1919 to Alcock and Brown for the first non-stop transatlantic flight between North America and Ireland.
