Vasily Alekseyevich Maklakov (Russian: Васи́лий Алексе́евич Маклако́в; May 22 [O.S. May 10] 1869, Moscow – July 15, 1957, Baden, Switzerland) was a Russian student activist, a trial lawyer and liberal parliamentary deputy, an orator, and one of the leaders of the Constitutional Democratic Party, notable for his advocacy of a constitutional Russian state. He served as deputy in the (radical) Second, and conservative Third and Fourth State Duma (Russian Empire). According to Stephen F. Williams Maklakov is "an inviting lens to which to view at the last years of Tsarism".
In February 1917 Maklakov was appointed as commissar in the Provisional Committee of the State Duma. In October 1917 he was sent to Paris as ambassador, but by the time he arrived there, the Russian Provisional Government no longer existed. He subsequently went on to organize the activities of Russian émigrés.
