Rebecca Jean Fink (née Smallbone; born 26 July 1977), known professionally as Rebecca Jean or Rebecca St. James, is an Australian American contemporary Christian singer, songwriter and actress. She began performing in Australia in the late 1980s and released her first full-length studio album in 1991. She was signed to ForeFront Records in 1993, releasing her major label debut the following year.

St. James rose to fame in the late 1990s with her RIAA certified Gold albums God and Pray, the latter of which won a Grammy Award in 1999 for Best Rock Gospel Album, and her holiday album Christmas. The albums spawned multiple singles, including "God", "Go and Sin No More", and "Pray". Since then she has established herself as one of the most prominent musical artists in Contemporary Christian music (CCM), with five additional full-length studio albums: Transform, Worship God, If I Had One Chance to Tell You Something, I Will Praise You, and Kingdom Come. Staple songs such as "Wait for Me", "Reborn", "Song of Love", "Alive", "Shine Your Glory Down", and "Battle Is the Lord's" have all been derived from these releases. She has earned nine No. 1 hits on Christian radio and has sold nearly two million albums since starting her career.

St. James is also an accomplished author and actress. To date, she has released over a dozen published books, narrated a documentary, and acted in nine films (including lead roles in Sarah's Choice and A Strange Brand of Happy), a musical stage show, and a VeggieTales episode ("An Easter Carol"). She is also an outspoken sexual abstinence and Pro-Life advocate, a spokesperson for Compassion International, the sister of Joel and Luke Smallbone, who comprise the band For King & Country, and the wife of Foster the People's former bassist Jacob "Cubbie" Fink.
