SEG Plaza (Chinese: 赛格广场) is a skyscraper in Shenzhen, Guangdong Province, China.

Completed in 2000 and located at the junction of Shennan Road and Huaqiangbei Electronics Market, it originally stood 356 metres (1,168 ft) tall including the height of the original antenna which has since been removed.

[1] The observation floor at the 69th level used to offer views over Shenzhen and northern Hong Kong but has been converted to office space.

[9] Authorities later declared the shaking as a result of winds which caused a rooftop mast to vibrate.

[10] The building's exact new height is uncertain, the original mast having accounted for approximately 210 feet (64 m) of it.
