Shenzhen Bay Sports Center (Chinese: 深圳湾体育中心), nicknamed Spring Cocoon (Chinese: 春茧) for its shape, is a multiuse stadium in Shenzhen, China. It is used mostly for table tennis, swimming and soccer competitions. The stadium is known for hosting the annual RoboMaster Robotics Competition since 2015, as well as the opening ceremony and some events of the 2011 Summer Universiade. The stadium has a capacity of 20,000 spectators and the Arena seats 13,000 more. The Sports Center also hosts regular concerts and has been used as a military staging area.

An international design competition for the building was held in early 2008, and preparatory work began in November of the same year. Built on reclaimed land, the foundations were laid in February 2009, and the building was completed in mid-2011. The building consists of three arenas, a swimming pool, an indoor arena, and a multi-use stadium joined by a perforated external steel skin. Within the complex is 30-story office tower.^[1][2]

The stadium is within walking distance from Houhai station of Shenzhen metro and is at the proximity of the Nanshan Central business district development.^[3]
