The Faculty of Engineering is as old as the University of Hong Kong . It was one of the three founding faculties set up when the University was first established in 1912. The Faculty presently contains five core departments: Civil Engineering, Computer Science, Electrical and Electronic Engineering, Industrial and Manufacturing Systems Engineering, and Mechanical Engineering.

The Department of Civil Engineering is one of the oldest departments in the University. Its postgraduate studies are offered either as predominantly research degrees, leading to the degrees of Master of Philosophy (MPhil) and Doctor of Philosophy (PhD) or primarily by coursework, leading to the degree of Master of Science (MSc) in Engineering. The Department also offers professional training courses for civil engineering graduates suitable for Continuing Professional Development for the purpose of obtaining corporate membership of the Hong Kong Institution of Engineers.

The Department of Computer Science was established in the Faculty of Engineering in 1988. The Department is active in both basic research in computer science and the development of computer technology. The Department offers programmes leading to MPhil and PhD degrees in Computer Science, a degree of MSc in Computer Science, and an MSc in Electronic Commerce and Internet Computing offered in conjunction with the Department of Electrical and Electronic Engineering.

The Department of Electrical and Electronic Engineering was established within the Faculty of Engineering in 1961. The Department offers postgraduate research programmes leading to the degrees of Master of Philosophy (MPhil) and Doctor of Philosophy (PhD) in areas of leading-edge technologies including wireless communications, computer systems and networking, energy systems and electric vehicle, microelectronics and VLSI, optoelectronics, signal and image processing, biomedical engineering, multimedia systems, control systems, and robotics and automation. The Department also offers an MSc(Eng) degree programme in Electrical and Electronic Engineering with three different streams, namely, General stream, Communications Engineering stream, and Computer and Information Engineering stream. In addition, the Department jointly offers an MSc(Eng) degree programme in Building Services Engineering with other departments in the Faculty.

The Department of Industrial and Manufacturing Systems Engineering offers research degrees programmes leading to Master of Philosophy (MPhil) and Doctor of Philosophy (PhD). Active areas of research in the Department include: logistics engineering, supply chain management, operations planning and management, facilities design, process planning and optimization, CIM, feature-based design, flexible manufacturing systems, robotic systems, inventory control, quality management, simulation, design of experiments, statistical process control, operations research, and plastics technology. The Department also offers an MSc(Eng) programme in Industrial Engineering and Logistics Management to provide training for practising engineers and managers.
