Monticelli is a small village, a frazione of the comune of Teramo in the Abruzzo region of Italy.
In 1062 Carbone di Solfio gave his holdings in the castle at Monticello, a small local church, and land in an area called Tricagli, to Pietro, bishop of Teramo.
On 30 April 1351, Queen Joanna I of Naples and her husband Louis of Taranto had Monticello, along with the neighboring communities of Ponzano, Varano and Tofo Sant'Eleuterio, incorporated into territory (at that time referred to as a Università) of Teramo.
Norman feudal records show Monticello and nearby Nepezzano under the tutelage of the Melatinos, a powerful family who dominated the area around Teramo, up until the 15th century.
In past times Monticelli probably served as a way station for vendors bringing their goods from the Vibrata Valley to sell in Teramo.
