"The Greatest" is a song recorded by Australian singer and songwriter Sia for the deluxe edition of her seventh studio album, This Is Acting (2016).

An accompanying music video for the single was filmed by Sia and Daniel Askill, and features American dancer Maddie Ziegler surrounded by 48 different young people.

[1] Although the singer has not provided an interpretation of the video's plot, numerous media outlets have perceived it as a tribute to the 49 victims of the Orlando nightclub shooting.

"[6] Once the critics had picked up on the song's connection with the Orlando nightclub shooting, Spencer Kornhaber of The Atlantic wrote: Making pop about a specific tragedy is necessarily a tricky job.

There's no break here from the rest of Sia's catalog about pain and release in everyday life: You hear a sad voice wailing about bucking up, very stark emotional peaks and valleys, and a danceable backing of explosive drums, toy-box melodies, and reggae grooves.

[7]The Orlando shooting commemoration was also praised by Bruno Russell from The Edge, who called the song's concept "inspirational" as "the message is clear: that we can make a difference and be 'The Greatest,' but we have to act now."

Online, Cosmopolitan, Variety, People magazine, concluded that the video was a tribute to the victims of the Orlando nightclub shooting.

The video opens with a low drone and cuts between shots of an upset Maddie Ziegler painting rainbow colours on her cheeks.

[21] On 7 September 2016, Sia, Ziegler and several other dancers performed "The Greatest" live for the first time at the 2016 Apple launch of the iPhone 7 at San Francisco's Bill Graham Civic Auditorium.
