The Super Bowl LI Halftime show took place on February 5, 2017, at NRG Stadium in Houston, Texas as part of Super Bowl LI. The show was headlined by Lady Gaga, who performed a medley of her songs, including newer material from her most recent album Joanne.

Gaga's performance was critically acclaimed, with media outlets praising the show for demonstrating her artistic and musical qualities, and some arguing that it ranked among the top Super Bowl halftime performances in history. The show was also noted for its acknowledgement of the LGBT community, the use of a swarm of lighting-equipped drones for a pre-recorded intro scene, and its perceived political undertones. With 117.5 million television viewers, the Super Bowl LI halftime show was the second-most-watched Super Bowl halftime show, and for the fourth consecutive year, garnered higher average viewership than the actual game. The NFL claimed, based on a composite of television, digital viewership, and social media content, that the Super Bowl LI halftime show was the "most-watched musical event of all-time".

The halftime show started on the roof of NRG Stadium with Gaga singing "God Bless America" with drones doing a light show of red, blue and white behind her. She then sings Woody Guthrie's "This Land Is Your Land", followed by part of the Pledge of Allegiance: "One nation under God, indivisible, with liberty and justice for all". Gaga then dived from the rooftop as the drones behind formed the design of the US flag. The singer came down and stood on a tall pillar across the stage, and started singing "Poker Face" as fireworks emanated behind her. After the first verse and chorus, Gaga again bounced from the pillar to the main stage, and was joined by her dancers to sing "Born This Way", including its intermediate spoken verse.
