"Let's Fall in Love for the Night" is a song by American singer-songwriter Finneas from his debut extended play (EP), Blood Harmony (2019).

Commercially, "Let's Fall in Love for the Night" peaked at number 17 and 24 on the US Billboard Alternative Songs and Rock Airplay charts, respectively.

It has received a gold certification by the Recording Industry Association of America (RIAA), Music Canada (MC) and ARIA.

"Let's Fall in Love for the Night" was released as the lead single on Finneas' debut extended play (EP), Blood Harmony, for digital download and streaming through his record label OYOY on October 19, 2018.

[8][9] Ben Kaye of Consequence of Sound commented that the instrumentation features "childlike piano notes echoing alongside Finneas' smooth vocals",[10] while Kate Brayden of Hot Press and Claire Shaffer of Rolling Stone mention Finneas sings over a "marimba and snap tracks".

[13] "Let's Fall in Love for the Night" starts with Finneas' "gentle whispered sweet nothings" vocals, then continues "into the heart of traditional song splendor".

[15] Nicole Almeida of Atwood Magazine defined the track as an "acoustic-guitar led song", and compared it to "Start of Something New" from the High School Musical soundtrack.

[15] Starr Bowenbank, writing for Billboard magazine, commented that "Let's Fall in Love for the Night" is a "testament to [Finneas'] songwriting talent".

[27] According to MTV, Finneas told them that the hardest part of filming the visual was the beginning scene, in which he sits on a little perch and strums his ukulele, then runs behind the camera to get to the other side of it, only to have to re-enter the frame looking like he did not even sweat slightly while sprinting.

Madeline Roth writing for MTV described that the video for "Let's Fall in Love for the Night" is "finally here for [our] viewing pleasure".

[30] Ahlgrim dubbed the visual as a "carefully choreographed dance number", noting that it opens with Finneas floating around a rooftop at dusk, smiling at the camera and fidgeting with his suit jacket, and described him as "deeply charming".

[33] In April 2020, Finneas performed an acoustic version of "Let's Fall in Love for the Night" during a 50-minute livestream for Verizon Communications and One World: Together At Home, respectively.
