"Arcadia" is a song by Lana Del Rey, from her eighth studio album and seventh major-label studio album Blue Banisters. It features writing and production credits from Drew Erickson and was released as a single on September 8, 2021.
Del Rey posted a snippet of the song to her social media accounts on July 3, 2021, with the caption, "Album out later later... Single out soonish." 
The title of the song was discovered through the copyright system on YouTube by fans uploading the snippet.
On September 3, 2021, Del Rey posted the single cover on her Instagram account and revealed that the song would be released the following Wednesday, on September 8. One day later a short new video snippet followed.
The version officially released on streaming services has a noticeably different instrumental than the version heard in the accompanying music video.
In an Instagram Live on October 22, Del Rey revealed that the song originated as a poem. She then said that she may still consider putting the poem in her upcoming poetry book, Behind the Iron Gates - Insights from an Institution. She also noted it was written in a motel after a breakup with a boyfriend, and it is her favorite track on Blue Banisters.

To tease the release of the song and music video, Del Rey shared three snippets on Twitter and Instagram: on July 3 and September 4 and 7, 2021 (the latter one being a silent clip). The official video was released on September 8, 2021, and features both "Arcadia" and "Interlude - The Trio". The same day, on Twitter, Del Rey stated that the video was "directed by nobody", and thanked "Charles Grant and Chris Ripley for their camera work". On October 7, 2021, an alternate one-shot music video was released without prior announcement.
