Hong Kong Special Administrative Region Establishment Day (Chinese: 香港特別行政區成立紀念日) is celebrated every 1 July, in Hong Kong since 1997. The holiday commemorates the transfer of the sovereignty of Hong Kong from the United Kingdom to the People's Republic of China and the establishment of the Hong Kong Special Administrative Region.

The day is customarily marked by an officially organised extravagant fireworks display in the evening, and is also the platform for political rallies demanding universal suffrage. In 2007, to commemorate the 10th Anniversary celebration the Hong Kong Government published a song, "Just Because You Are Here" (Chinese: 始終有你). It was sung by many Hong Kong singers and composed by Peter Kam (金培達) with lyric by Keith Chan (陳少琪).
