Alfonso Beorlegui y Canet (26 January 1888 – 29 September 1936) was a colonel of infantry in the Spanish Army.

In the Spanish Civil War, he led the Nationalist forces in the Campaign of Gipuzkoa in August and September 1936.

Shortly afterward, Mola ordered Beorlegui to lead an offensive to the Basque province of Gipuzkoa with the regular troops, Civil Guard forces and some newly raised units of requetés.

After the Battle of Irún, they occupied the town on 5 September, closing the French border to the northern provinces of the republic.

Beorlegui was wounded in the advance towards the international bridge of Irún, refused to receive suitable treatment, and died a month later.
