Alphonse Léopold Bauduin Six (1 January 1890 – 19 August 1914) was a Belgian football player.

Due to Union SG not keeping their promises about a job for him - professional footballers were unheard of at that time - he moved to Olympique Lillois, a predecessor of Lille OSC.

That season he became the first Belgian football player to become a champion in a foreign country.

After the fall of the forts in Liège, King Albert I pulled his troops back to Antwerp.
