Morro d'Oro is a town and comune in Teramo province in the Abruzzo region of eastern Italy.

Its territory extends for 28.18 km²; the inhabitants at the census of 21 October 1991 were 3,015 units; as of 31 December 1995 there were 3,190; a sign that the municipality, after a twenty-year phase of depopulation (from 3,215 in 1961 to 2,758 in 1981) is in continuous demographic growth.

All this thanks to its strategic location (12 km from the sea and 40 from the mountain) and its changed economic conditions: from an exclusively agricultural economy - and mainly sharecropping - to a more integrated agricultural-artisan-industrial one.

Therefore, its economy is based, on the one hand, on agriculture, but of an advanced type and on selected crops (vegetables and orchards), in addition to the traditional ones: cereals in general; on the other, on the tertiary sector (building craftsmanship and, to a lesser extent, trade); but there is also adequate industrial development, which absorbs a workforce of around 300 units.

The origins of Morro d'Oro date back to the Middle Ages: probably linked to the era of castles (8th-10th century); but, evidence of its existence is not available before a document from 1021, which speaks of a donation made by Adelberto De Aprutio in favor of the monastery of Montecassino and in which the estate of Muro appears and mentions of a Castello Veccio.
