Elbernita "Twinkie" Clark is an American gospel singer, composer, musician, and evangelist. She is a member of The Clark Sisters, an influential gospel vocal ensemble active since the late 60's.

Clark has been The Clark Sisters' creative force since their mother Mattie Moss Clark turned over control of the group to her in the early 1970s. An accomplished pianist and organist, Clark received formal training in piano from Howard University and is dubbed as the "Queen of the Hammond B3" organ. She has written over 150 songs for her sisters and mother alone.

Clark was one of the first to add jazz, reggae, hip-hop, and blues to gospel music. This is evidenced by listening to her first two solo albums Praise Belongs To God and Ye Shall Receive Power recorded for Sound of Gospel Records while still with The Clark Sisters. Twinkie Clark is an avid Stevie Wonder fan, her most popular song "You Brought The Sunshine" was partially inspired by the motif of Stevie's "Master Blaster (Jammin')".

Twinkie left the Clark Sisters in 1989 to focus on ministry and family. Twinkie recently reunited with The Clark Sisters in July 2006 to record a new live album, The Clark Sisters- Live:One Last Time, was released by EMI Gospel in March 2007.
