Alfredo Di Dio (4 July 1920 – 12 October 1944) was an Italian officer and Resistance leader during World War II.

Subsequently, Di Dio decided, in agreement with Beltrami, to go to Milan to obtain funding for training from the National Liberation Committee.

On 23 January, Alfredo left with his escort for Milan, but there he was captured by the Fascists and imprisoned in Novara; while he was in prison, his partisan group suffered a severe blow as his brother Antonio and Beltrami were killed in combat in Megolo on 13 February.

The unit, of Catholic orientation, was later enlarged and renamed "Valtoce" Division, and would grow to a force of 20,000 men in 1945; its members wore a blue handkerchief around their necks.

In August-September 1944 Di Dio and the "Valtoce" Division played a large role in the liberation of Domodossola from the Germans and Fascists and in the establishment of the Republic of Ossola.
