"1-800-273-8255" is a song by American rapper 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. The song's name is the phone number for the National Suicide Prevention Lifeline. Produced by Logic and 6ix, 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?

The song's accompanying music video premiered on August 17, 2017, on Logic's Vevo channel on YouTube. The music video was directed by Andy Hines and centers around a young man who struggles with feeling accepted due to his sexuality. The video features cameo appearances from Coy Stewart, Nolan Gould, Don Cheadle, Luis Guzmán and Matthew Modine.
