YuiKaori (ゆいかおり) is a Japanese pop idol duo under KING RECORDS consisting of well-known voice actresses Ogura Yui and Ishihara Kaori. The duo was formerly a sub-unit of HAPPY! STYLE before its members left UP-FRONT STYLE in 2011. Afterwards, they became their own unit under another agency, Style Cube. The duo debuted in May 2010 with the release of their first single Our Steady Boy, which also acted as the ending theme for the anime Kiss × Sis. Later in 2013, the duo left Style Cub and signed under the voice acting agency Sigma Seven. 

As a duo, the two often voiced characters in the same television anime shows or video games, and their songs nearly always had an anime or video game tie-in. 

YuiKaori's highest selling single is Intro Situation with 10,334 copies sold. YuiKaori's lowest selling single is Futari / VIVIVID PARTY! with 927 copies sold.

Shortly after the release of their compilation album Y&K, the duo announced that they had disbanded on June 30, 2017 so that they both could focus on their solo careers.

After their disbandment, they both remained active as voice actresses, with Ogura Yui continuing her already established solo singing career under KING RECORDS, and Ishihara Kaori officially launching her own solo career under the Pony Canyon label in 2018.
