Albert Charles Dubly (2 September 1881 – 23 December 1949) was a French footballer who played as a defender for RC Roubaix in the early 20th century.

[7] Out of the nine brothers, seven played football, from which the eldest two, Maurice and Léon, were pioneers; the youngest two, Jean and Raymond, were the most technically gifted, while the three from the middle, Albert, André, and Pierre, had a more discreet career.

[8] Like his older brothers, Dubly began playing football at Racing Club de Roubaix, and together with Maurice, Léon, André Renaux, André François, and Émile Sartorius, he was a member of the Roubaix team that won a three-peat of French national championships between 1902 and 1904, with Léon and Albert starting in each of those three finals; the former was the captain in the 1902 final, scoring the opening goal to help his side to a 4–3 win over Racing Club de France after a long extra-time.

[6][10] In the preview of the 1903 final, the French newspaper L'Auto (the future L'Équipe) described him as "tough, precise, and conscientious player who could perhaps be blamed for his lack of speed".

[11] In 1904 final, he was replaced by his younger brother André, who helped his side to a 4–2 win over United Sports Club [fr]; this was the retirement match of captain Léon, who was set to get married wthin two weeks.
