Miss Love Tantei (Ｍｉｓｓラブ探偵; Miss Love Detective) is the sixth single by the Hello! Project duo, W. The single was released on September 7, 2005, and the single V was released on September 14, 2005. "Miss Love Tantei" is W's last single, as their followup single, Dou ni mo Tomaranai, would be canceled after Kago Ai's 2006 hiatus and subsequent release. It is also their lowest selling single.
"Miss Love Tantei" appears on the Hello! Project compilation album Petit Best 6. Fans speculate that it was planned to be part of W's unreleased third album.
