Czesław Młot-Fijałkowski (1892–1944) was a Polish military officer and a brigadier general of the Polish Army.

Czesław Fijałkowski was born April 14, 1892 in Okalewo (now in Rypin County), then part of the Russian Empire. In 1912 he graduated from a trade school in Skierniewice and left Congress Poland for Liège, where he joined the Leodium University. There he joined the Polish Rifle Squads organization and became the head of its local branch in Belgium. Following the outbreak of World War I he returned to Poland and joined the Polish Legions already in August 1914. He served on the front, commanding a platoon, a company and eventually a battalion of the 5th Legions' Infantry Regiment. Around that time he earned the nickname of Młot (Polish for Hammer), which afterwards became part of his surname. Following the Oath crisis of 1917 he was interned in Beniaminów, but was released in May 1918 and was allowed to join the Polnische Wehrmacht, at the same time secretly cooperating with the Polish Military Organization.
