Sunshine City (Chinese: 新港城) is a private housing estate in the town centre of Ma On Shan in the Sha Tin District of Hong Kong.

It was developed by Henderson Land Development, and contains a series of 20 high-rise residential tower blocks[1] and a series of shopping arcades.

The shopping centres for phases 1 to 3 are relatively small.

MOSTown, formerly named Sunshine City Plaza (新港城中心), the shopping arcade built with phase 4, is by far the largest, and has retail floor space of in excess of 175,000 square metres (1,880,000 sq ft).

Sunshine Bazaar (新港城廣場) is the name given to Phase 5 of the mall.
