Dywizja Piechoty) was a tactical unit of the Polish Army during the early stages of World War II.

During peace time the unit existed only on paper, as part of the mobilization scheme accompanying the Plan West.

The division was finally created on 24 August 1939 as part of the secret mobilization preceding the outbreak of World War II.

Although not yet fully formed the fast pace of German advance during the invasion of Poland meant that the division was dispatched to the front by 4 September 1939 and took over the task of screening the area around Różan, along the Narew river.

On 5 September 1939 the German "Wodrig" Corps (1st and 12th Infantry Divisions), having broken through Polish positions in the Battle of Mława, assaulted Różan directly.

As the bridge at Brok had been demolished by Polish sappers prematurely, the disorganized regiments of the 41st Division had to continue the withdrawal west towards Wyszków, losing many more men in the process.
