Ġużepp Portelli (8 December 1880 - 7 March 1949) was a Maltese Roman Catholic prelate who founded the present Ta' Pinu Basilica in Gozo.

Monsignor Portelli was also a renowned preacher who was often invited to deliver sermons and spiritual exercises in several churches in Malta and Gozo.

Monsignor Portelli served as administrator of Ghasri, Nadur, Qala and Ta 'Sannat when the post of parish priest became vacant.

In 1933, several centres of Catholic Action started to emerge in Gozo and Monsignor Portelli became the Spiritual Director of the branch of Għarb.

On June 16, 2008, the remains of Monsignor Portelli were reburied inside the Basilica of Ta' Pinu.
