"Chiisana Koi no Uta" (Japanese: 小さな恋のうた; lit. A Small Love Song) is a Japanese rock song written and performed by the Japanese punk band Mongol800. It is featured on their second studio album Message which was released in Japan on September 16, 2001. The song's lyrics are about the love between a boy and a girl who have grown up on a small island.

Despite not being released as a single, "Chiisana Koi no Uta" became one of Mongol800's most well-known songs and has been covered numerous times, most popularly by Amatsuki in 2016. Other cover versions include the insert song for Kase-san and Morning Glories performed by Ayane Sakura. Rie Takahashi performed the song for Teasing Master Takagi-san in 2018, while Manaka Iwami performed the song for The Angel Next Door Spoils Me Rotten in 2023 and Sumire Uesaka for Alya Sometimes Hides Her Feelings in Russian in 2024. The song inspired the production of a live-action movie of the same name, released in May 2019 by Toei.

The song is a popular karaoke song in Japan, ranking first in the DAM karaoke ranking. It is the second song of the 2000s to accumulate 100 million streams after "Hanabi" by Mr. Children. Music critic Tomonori Shiba said the song became popular because of its easy to understand lyrics and simple chord progression.
