"Deep Inside" is a song by the American singer Mary J. Blige. It was written by Blige, Tara Geter and Kevin Deane for her fourth studio album, Mary (1999), while production was led by Deane. The song features a sample of piano playing from Elton John's "Bennie and the Jets" (1974). John and co-writer Bernie Taupin are also credited as songwriters.

The song was released as the second US single from Mary, and the third single elsewhere. Like the preceding single, "All That I Can Say" (1999), it was a moderate success in the United States, peaking at number fifty-one on the Billboard Hot 100. In the United Kingdom, it failed to reach the UK top 40. The music video for "Deep Inside" has Blige and her dancers performing to the song "Sincerity", which appears on the deluxe edition of the Mary album in the United States and the United Kingdom single of "Deep Inside".
