Britney was just 16 when the song was released on 23 October 1998. It reached number one in at least 18 countries, including the UK.
She became a global superstar and went on to have hits including Toxic, Womanizer and Oops!...I Did It Again.
In the post, Britney said: "It's hard to put into words what today means to me… 20 years ago, the world heard my music for the very first time!
"So much has happened since then… but what I really want to say is thank you to my amazing fans who have been there for me since day one."
The 36-year-old has had some highs and lows over her 20-year career.
In 2007, she had a string of high-profile public spats, paparazzi run-ins and family feuds.

To mark 20 years since ...Baby One More Time, Deezer revealed her most-streamed song of 2018 was her 2004 hit Toxic.
Its data showed that 28% of people listening to her tracks this year were aged between 18 and 24 - so some of them wouldn't have been alive when she released her first single.
