"1-800-273-8255" is a song by American hip hop artist Logic. It was released on April 28, 2017, through Visionary Music Group and Def Jam Recordings, as the third single from his third studio album Everybody.[1] The song's name is the phone number for the National Suicide Prevention Lifeline.[2] Produced by Logic and 6ix,[3] the song features guest vocals from singer-songwriters Alessia Cara and Khalid.

In an interview with Genius, Logic said:

So the first hook and verse is from the perspective of someone who is calling the hotline and they want to commit suicide. They want to kill themselves. They want to end their life. When I jumped on a tour bus that started in Los Angeles, California and I ended in New York City and did a fan tour where I went to fan's houses and shared meals with them, hung out with them, played them my album before it came out. Them along with other people on tour, just fans that I met randomly, they’ve said things like, "Your music has saved my life. You've saved my life." And I was always like, "Aw so nice of you. Thanks." And I give them a hug and shit but in my mind, I'm like, "What the fuck?" And they're really serious. And they tat shit on their arms and get shit like lyrics that save their life and in my mind, I was like, "Man I wasn't even trying to save nobody's life." And then it hit me, the power that I have as an artist with a voice. I wasn't even trying to save your life. Now what can happen if I actually did?

"1-800-273-8255" debuted at number 61 on the US Billboard Hot 100 and number 67 the Canadian Hot 100 for the chart dated May 20, 2017.[8][9] Following the album's release it went up to number 47 and 40 respectively.[10][11] On September 25, 2017, the single was certified Double Platinum by the Recording Industry Association of America (RIAA) for combined sales and streaming equivalent units of over 2,000,000 units in the United States. Following the song's performance at the 2017 MTV Video Music Awards, the song jumped to number nine, becoming Logic and Khalid's first top 10 single, and Alessia Cara's fourth. It later reached the top three on the Billboard Hot 100, becoming all three's top charting single.

According to the National Suicide Prevention Lifeline (NSPL), in the three weeks following the single's release, calls directed to the NSPL rose by 27%, while visits to their website increased from 300,000 to 400,000 over the following months.[12]

Lifeline's Director of Communications Frances Gonzalez reported that, following the night of the 2017 MTV Video Music Awards, the NSPL experienced a 50% surge in the number of calls to their hotline. This was reportedly as a result of the performance of the song by Logic, Cara, and Khalid during the show as well as the speech given by recording artist and activist Kesha, who was tasked with presenting the performers.
