Arbeiter-Samariter-Bund Deutschland or ASB (English: Workers' Samaritan Foundation Germany) is a German charitable aid agency founded in 1888.

In the summer of 1881, the German surgeon Friedrich von Esmarch (1823-1908) met St John's Ambulance Association leadership in London and founded a Samaritan school on his return to Germany.

Numerous notes from the German-Samaritan-Federation were subsequently issued; however, they were directed primarily to senior health officials and were inclusive of the broad mass of workers.

In 1888, six carpenters in Berlin took the initiative and set up the first course on the First Aid in the event of a disaster on 29 November 1888, and founded the first column of what would become the Workers' Samaritan Federation Germany.

With the establishment of the Federal Republic of Germany, the ASB developed supra-regional structures.
