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 released due to the termination of Kago Ai's contract in 2007. It was also their lowest selling single, presumably due to controversy (see below) and the year-long hiatus caused by Kago Ai's suspension for underage smoking in 2006.
"Miss Love Tantei" had not been included on an W album, and some speculated it would have been part of their cancelled W3:faithful album. The song does, however, appear on the Hello! Project compilation album Petit Best 6.
"Miss Love Tantei" faced criticism due to its sampling of the t.A.T.u. song "Not Gonna Get Us". The music video also faced criticism because of a scene where Tsuji and Kago appeared with tanned skin and white lips, traits of the controversial ganguro look.
