Lorenzo D'Astiria (1604 - 5 January 1678) was a Spanish Roman Catholic bishop of Malta in the 17th century.

It is reported that on this visit Bishop D'Astiria gave permission for the reopening of the church which had been closed.

This took place because a certain Petronilla Pontremoli promised to celebrate the feast of Our Lady and to distribute bread to all the poor.

[2] It is recorded that on 30 September 1671 Bishop Lorenzo D'Astiria made a pastoral visit to Mqabba.

Bishop D'Astiria is also responsible for the reopening of the chapel of the Assumption, nowadays known as Ta' Pinu in Għarb, Gozo.
