Cagayan's 1st congressional district

Cagayan's 1st congressional district is one of the three congressional districts of the Philippines in the province of Cagayan. It has been represented in the House of Representatives of the Philippines since 1916 and earlier in the Philippine Assembly from 1907 to 1916. The district consists of Cagayan's former capital, Lal-lo, and adjacent municipalities of Alcala, Aparri, Baggao, Buguey, Camalaniugan, Gattaran, Gonzaga, Santa Ana and Santa Teresita. It is currently represented in the 19th Congress by Ramon C. Nolasco Jr. of the Nationalist People's Coalition (NPC).

Prior to its second dissolution in 1972, the first district consisted of eastern and northern Cagayan municipalities of Alcala, Amulung, Aparri, Baggao, Ballesteros, Calayan, Camalaniugan, Gattaran, Gonzaga, Iguig, Lal-lo, Peñablanca, Santa Ana, Santa Teresita, and Tuguegarao, the provincial capital. The province of Batanes was also part of the district from 1907 to 1909. Following the restoration of the Congress in 1987, the district was reapportioned to its current composition.
