The toponym Boac is derived from the Cebuano word bu ak, cognatic to the Tagalog word bi ak and the southern Tagalog term ba ak. This is in reference to the town being bisected by the Boac River which runs from the Central Marinduque and Balagbag Mountain Ranges to the west coast facing the Tayabas Bay and Sibuyan Sea.

During the Spanish colonization, the first visita called Montserrat de Marinduque was established in the island in 1580 in what is now Boac.

In the early years of Spanish colonization in Marinduque, it was first mentioned in Miguel de Loarca's Relacion de las Yslas Filipinas (1582 1583) that the natives of the island are Pintados or tattooed people resembling those from the Camarines Provinces and the Visayan Islands. In 1580, the first visita was established in the island of Marinduque and was called Montserrat de Marinduque in what is now the municipality of Boac; this visita was governed by Fray Alonzo Banol as minister. In 1621, Spanish Jesuit missionaries brought a three foot Marian image to Boac which will later be known as the Mahal na Ina ng Biglang Awa. Notorious for their sea raids, a group of Muslim pirates from the southern Philippines sieged Boac in the mid 17th century along the shores of Laylay and eventually into the Poblacion located along the Boac River. In panic, the locals took refuge in the fortress church of Boac as able bodied men defended the outer walls against the attacks. Many locals were killed and, by the third day of siege, the surviving locals began to run short on food and the capture of the fortress became imminent. As an act of faith, the survivors prayed fervently at the throne of Mary, asking her to deliver them from these enemies. According to legends, a very strong storm with torrential rain, thunder, and lightning engulfed the area and at its very height, it was reported that the image of a beautiful lady with outstretched arms appeared standing on the top of the fortress wall. Terrorized, the pirates fled in confusion to their vintas and left the island.
