The Subic–Clark–Tarlac Expressway (SCTEX), signed as E1 and E4 of the Philippine expressway network, is a controlled-access toll expressway in the Central Luzon region of the Philippines. From its northern terminus in Tarlac City to its southern terminus at Tipo in Hermosa, Bataan, the SCTEX serves as one of the main expressways in Luzon. The expressway is also connected to the Central Luzon Link Expressway, North Luzon Expressway, Tarlac–Pangasinan–La Union Expressway, and the Subic Freeport Expressway.
