Qihao Weng (born June 1964) is an American geographer, urban, environmental sustainability, and remote sensing scientist.

After working as a middle school teacher for three years, he went to Guangzhou, studied and received a master's degree from South China Normal University in Physical Geography in 1990.

He was a National Director of the American Society for Photogrammetry and Remote Sensing, 2007–2010, representing the Western Great Lakes Region.

He started to work at the Hong Kong Polytechnic University in July 2021 as a Chair Professor of Geomatics and Artificial Intelligence, and was awarded a Global STEM Professorship.

[25] His research has also demonstrated that urban sprawl and warming are not an isolated phenomenon, but instead are coupled with other risk factors, such as infectious diseases.

These are the types of techniques required to develop a remote-sensing based approach that can provide better outputs to address the important themes of climate, health, energy use, hydrology and hazards assessments in urban areas.
