The Cavite–Laguna Expressway, signed as E3 of the Philippine expressway network, is a partially operational controlled-access toll expressway in the provinces of Cavite and Laguna, Philippines. The construction of the 44.63-kilometer-long (27.73 mi) expressway, which began in June 2017, costs an estimated ₱35.43 billion. Once completed, it will connect the Manila–Cavite Expressway in Kawit to the South Luzon Expressway in Biñan and is expected to ease the traffic congestion in the Cavite–Laguna area, particularly along the Aguinaldo Highway, Governor's Drive, and the Santa Rosa–Tagaytay Road.

The Philippine expressway network, also known as the High Standard Highway Network, is a controlled-access highway network managed by the Department of Public Works and Highways (DPWH) which consists of all expressways and regional high standard highways in the Philippines.
