A Symphony of Lights 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 symphonic 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.

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

Organised by the Hong Kong Tourism Board. Displayed every night with good weather at 8pm Hong Kong Time, the show is 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 Harbor. 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.

Special pyrotechnic fireworks will be added to the show on the rooftop of participating buildings on both sides of the habour or stages off at the Tsim Sha Tsui waterfront. It will be added on special events or holidays, example like Chinese New Year and Christmas.
