Biuletyn Informacyjny ("Information Bulletin") was a Polish underground weekly published covertly in General Government territory of occupied Poland during World War II.

The magazine was edited by Aleksander Kamiński and distributed as the main organ of ZWZ-AK headquarters in Warsaw, initially in order to inform the AK soldier about ongoing resistance activities.

[2] The Bulletin was started in November 1939 in Warsaw as the main press release of the SZP, the first underground resistance organisation in Poland.

Our battle in the capital, in the face of death and destruction, stands in the forefront of famous deeds of Polish soldiers during this war.

Although we were not able to gain a military victory over our enemy (since the general situation in our country was not favourable to our endeavour), those two months of fighting for every foot of Warsaw's streets and walls have fulfilled a political and ideological goal.
