Jalan Cengai is a minor road in the Fettes Park neighbourhood of Tanjong Bungah, Penang. It connects on one end to Jalan Gajah. A major portion of Jalan Cengai is now within the grounds of College General.
Jalan Cengai is possibly named after the cengal, a hardwood tree that is common in Malaysia. It is also known by the scientific name Neobalanocarpus and is today an endangered tree in Malaysia.
