Barangka is an administrative division of Marikina, Metro Manila, the Philippines. It is an urban barangay part of the 1st district of Marikina and is one of the oldest barangays in Marikina.
Located along the southwestern border of Marikina, with the Marikina–Infanta Highway and A. Bonifacio Avenue, which serve as thoroughfares connecting Quezon City and Marikina, and with the municipalities of San Mateo and Rodriguez (Montalban) in Rizal to the east, Barangka is considered to be a gateway for people going to and from Metro Manila and Rizal. It is bordered on the west by barangay Loyola Heights in Quezon City; to the south by barangays Industrial Valley and Calumpang; to the east by barangay Tañong; and to the north by Loyola Grand Villas.
Barangka takes its name from the Spanish word for "canyon", barranca, owing to the area's steep and hilly terrain. The area of Barangay Barangka is considered one of the earliest historical origins of Marikina when the Augustinians and Jesuits arrived in the area called chorrillo, a small stream located in the area (now called Chorillo, a known street located in this barangay). From 1939 to 1941, the sitio was under the jurisdiction of the then-newly established Quezon City before it was returned to Marikina.
Along with former Parang and Nangka, the former sitio was elevated to barangay by virtue of Republic Act No. 2601, which was enacted on June 21, 1959.
Barangka lies on the foothills of Quezon City and also over the West Valley fault systems. It has a total land area of 116.96 ha (1.17 km2) with a population of 27,805, making it the mostly densely populated barangay in Marikina. The Marikina River where the Marikina River Park and Riverbanks Center is located borders the barangay to the south.
