"Saraba, Itoshiki Kanashimitachi yo" (サラバ、愛しき悲しみたちよ^?, "Farewell, My Dear Sorrows") is the 9th single by the Japanese female idol group Momoiro Clover Z, released in Japan on November 21, 2012. The title track became the group's first song to top the Billboard Japan Hot 100 chart.

The single was released in two versions: a limited edition and a regular edition. The limited edition comes with a DVD featuring the music video for the title track, but contains less songs on the CD in comparison to the regular CD-only edition.

The title track is a theme song of the Nippon Television family drama series Akumu-chan starring Keiko Kitagawa. The song is composed and arranged by Tomoyasu Hotei.

The regular edition's B-side "Wee-Tee-Wee-Tee" is sung in Japanese and Furbish. It is an advertising song for Furbies. The word wee-tee means "sing" in the Furbish language, and the title is translated in different Japanese news publications as either "Sing, Sing" or "Let's Sing!".

The cover's theme is "good and evil". On the regular edition's cover the Momoiro Clover members are wearing white costumes and on the limited edition's — black, representing two outlooks on the world.

The music video for the title track elaborates further on the song's theme. In it, the girls are also wearing two types of clothes, black and white. They change between angel and demon costumes when switch between the voice of their conscience and the whispers of Satan. The video was directed by Hideki Kuroda, who notably shot music videos for such artists as SMAP and Southern All Stars.
