A Symphony of Lights (Traditional Chinese: 幻彩詠香江) is a synchronised building exterior decorative light and laser multimedia display, featuring 44 buildings on both sides of the Victoria Harbour of Hong Kong accompanied by music. The technology was developed by Australian firm Laservision and cost approximately 44 million HK dollars. It has attracted over 4 million visitors and locals so far, and is held every night for ten minutes.

Guinness World Records has named A Symphony of Lights the world's largest permanent light and sound show.

The show is organised by the Hong Kong Tourism Board and displayed every night with good weather at 8pm Hong Kong Time. An orchestration of music, decoration lights, laser light displays, and pyrotechnic fireworks, the multimedia light and sound show lasts for about 14 minutes.

The best vantage points include the "Avenue of Stars" on the Tsim Sha Tsui waterfront, on the waterfront promenade outside the Golden Bauhinia Square in Wan Chai and on sightseeing ferries (i.e. Star Ferry) running across the Victoria Harbour. The Show's music and narration live at the "Avenue of Stars" and the promenade outside the Golden Bauhinia Square in Wan Chai every night. On Mondays, Wednesdays and Fridays the narration is in English, while it is in Mandarin on Tuesdays, Thursdays and Saturdays, and Cantonese on Sundays.
