Alois Windisch (3 February 1892 – 28 December 1958) was an Austrian general in the armed forces of Nazi Germany during World War II.

Promoted to captain in 1921 (1 January 1921), he was selected for General Staff Training and graduated on top of his class.

A full colonel in the Austrian General Staff since 1936 (promotion 24 June 1936) and senior tactics teacher, Windisch was well known for his refusal of the Nazi movement.

After the Nazi take over in Austria (13 March 1938), he was considered "politically unreliable", expelled from the General Staff Corps, put on administrative leave and earmarked for forced retirement.

The beginning of World War II (1 September 1939) and the resulting need for experienced military leaders led to his assignment as commanding officer of a Mountain Infantry Regiment (Gebirgsjäger-Regiment 139).
