Sumulong Highway, constructed in 1960, is the highway in the Philippines that connects Marikina with Antipolo and the municipalities of Teresa and Morong in the province of Rizal. It was named after Don Juan Sumulong, a former President of the Democrata Party.
Near the boundary of Antipolo with Marikina the highway meets the Marikina-Infanta Highway, the highway that connects Metro Manila with the northern towns of Infanta and General Nakar in the province of Quezon. It is sometimes referred in media as the "killer highway"  due to the number of accidents that have taken place on it.
