The province of L'Aquila (Italian: provincia dell'Aquila) is the largest, most mountainous and least densely populated province of the Abruzzo region of Italy. It comprises about half the landmass of Abruzzo and occupies the western part of the region. It has borders with the provinces of Teramo to the north, Pescara and Chieti to the east, Isernia (in Molise region) to the south and Frosinone, Rome and Rieti (in Lazio region) to the west. Its capital is the city of L'Aquila.

The province of L'Aquila includes the highest mountains of the Apennines (Gran Sasso, Maiella and Velino-Sirente), their highest peak, Corno Grande, the high plain of Campo Imperatore, and Europe's southernmost glacier, the Calderone. The province's major rivers are the Aterno-Pescara, Sangro, Liri, Salto, and the Turano; its major lakes are Lago Scanno and Lago Barrea. It once included the third largest lake on the Italian peninsula, Lago Fucino, which was drained in one of the 19th century's largest engineering projects. The lake basin is today a flourishing agricultural area and an important technological district.

The Hernici were an Italic tribe of ancient Italy, whose territory was in Latium between the Fucine Lake and the Sacco River (Trerus), bounded by the Volsci on the south, and by the Aequi and the Marsi on the north.

Marsica is a geographical and historical region in Abruzzo, central Italy, including 37 comuni in the province of L'Aquila. It is located between the plain of the former Fucine Lake, the National Park of Abruzzo, Lazio and Molise, the plain of Carsoli and the valley of Sulmona.

The area takes its name from the Marsi, an Osco-Umbrian Italic people, and then from the Latin adjective marsicus. In the center of the area there is the Fucino former lake, dried up in 1877, surrounded by parks and nature reserves. Avezzano is the most populous city of the territory. Marsica has about 130,000 inhabitants as of 2019.

The Marsi were an Italic people of ancient Italy, whose chief centre was Marruvium, on the eastern shore of Lake Fucinus (which was drained in the time of Claudius). The area in which they lived is now called Marsica. They originally spoke a language now termed Marsian which is attested by several inscriptions.
