"Ren'ai Hunter" (恋愛ハンター^?, Ren'ai Hantā, "Love Hunter") is the 49th single by the Japanese female idol group Morning Musume, released in Japan on April 11, 2012.

"Ren'ai Hunter" is the second single for the 10th generation members and the last single by Morning Musume to feature Risa Niigaki. It also became the last single to feature Aika Mitsui, who would announce her graduation from the group due to a foot injury that was taking a long time to recover.

The single will be released in six versions: a regular edition and five limited editions. The Regular Edition and the Limited Editions D and E are CD-only. The Limited Editiona A, B, and C come with a DVD containing a special version of the music video for the title song.

The Limited Edition E is a special version to commemorate Risa Niigaki's graduation from Morning Musume. It contains an additional song, performed by her. The song is a cover of "Egao ni Namida (Thank You! Dear My Friends)" from Aya Matsuura's 2002 album First Kiss. As the group's producer Tsunku wrote in his comment about the single, the song is Risa Niigaki's favourite, although it is not a Morning Musume's song; she would always listen to it at the time when she was still a freshly joined member.

All the limited editions include an entry postcard for a lottery to win a ticket to one of two single's launch events; one will be held on April 28 in the Kansai region, and the other on May 3 in the Kanto region. So, the Limited Edition D contains the same tracks as the Regular Edition, but sports a different cover and includes a lottery card.

The title track is an electropop song with a dubstep-influenced arrangement.
