"Uchōten Love" (有頂天LOVE, Uchōten Rabu) is the 6th major single by the Japanese girl idol group S/mileage. It was released in Japan on August 3, 2011 on the label Hachama.

The physical CD single debuted at number 4 in the Oricon daily singles chart.

In the Oricon weekly chart, it debuted at number 5.

The B-side of the regular edition was a cover of the song "Chu! Natsu Party", originally released as a single by a temporary Hello! Project group 3nin Matsuri. By that time it had already been covered by Berryz Kobo on their 2006 mini album 3 Natsu Natsu Mini Berryz.

The single was released in five versions: four limited editions (Limited Editions A, B, C, and D) and a regular edition.

All the limited editions came with a sealed-in serial-numbered entry card for the lottery to win a ticket to one of the single's launch events.

The corresponding DVD single (so called Single V) was released 1 week later, on August 10, 2011.
