A third class municipality with an area of 92,060 hectares. It was once a barangay of Amulung but due to a Royal Degree on November 27, 1896, it was separated from Amulung. Don Rafael Catolico became its head in 1899 making Baggao automatically a "pueblo."

Bounded by the Sierra Madre Mountain and the Pacific Ocean, Baggao also boasts of several scenic spots like the seven Steps at Gimuno, Duba Summer Resort and the hot spring at Intal, to name a few.

The inhabitants were from the early Indonesian immigrant to the present-day Ybanag, Kalingas and the migrant Ilocanos who introduced the tobacco crop.

As more settlers poured in, a Spanish Missionary was assigned in the person of Fray Pedro Vicandi, O.P. He directed the construction of a chapel atop the hill overlooking the village.

The most important products are rice, corn, tobacco, mongo and lumber. The chief occupation of the people is farming.

Baggao is the birthplace of Msgr. Teodolfo S. Domingo, D.D. He is the first native bishop of the Tuguegarao Diocese, and was consecrated on July 2, 1957 by Msgr. Egidio Vaquozzi, Papal Nuncio.
