If You Only Knew is the second album by American R&B singer Gina Thompson. It was scheduled to be released through Elektra Records/East West Records on September 21, 1999, however it was shelved due to the failure and lack of commercial success for her lead singles, "Ya Di Ya" (#38 U.S. R&B) and "Caught Up". The album, however, was released by Elektra Records for a limited time, due to the lukewarm success of "Ya Di Ya".
