Huawei Technologies Co., Ltd. is a Chinese multinational technology corporation headquartered in Shenzhen, Guangdong, China. It designs, develops, produces and sells telecommunications equipment, consumer electronics and various smart devices.

The corporation was founded in 1987 by Ren Zhengfei, a former officer in the People's Liberation Army (PLA). Initially focused on manufacturing phone switches, Huawei has expanded its business to include building telecommunications networks, providing operational and consulting services and equipment to enterprises inside and outside of China, and manufacturing communications devices for the consumer market.

Huawei has deployed its products and services in more than 170 countries and areas. It overtook Ericsson in 2012 as the largest telecommunications equipment manufacturer in the world, and overtook Apple in 2018 as the second-largest manufacturer of smartphones in the world, behind Samsung Electronics. In 2018, Huawei reported annual revenue of US$108.5 billion. In July 2020, Huawei surpassed Samsung and Apple in the number of phones shipped worldwide for the first time. This was primarily due to a drop in Samsung's global sales in the second quarter of 2020, owing to the impact of the COVID-19 pandemic.
