"I Believe" is a song by American singer-songwriter Marcella Detroit, released on February 28, 1994, via London Records as the lead single from her second studio album, Jewel (1994).

"[2] Larry Flick from Billboard wrote, "Shakespear's Sister siren steps solo with an airy pop ballad that shows recently undisplayed vocal depth and power.

Fleshed-out, lush synths and plucky sitar riffs will remind some of Annie Lennox's Diva musings in the most positive way, while others will tap into the unique style that Detroit has developed.

"[4] Chuck Campbell from Knoxville News Sentinel felt the singer "grandstands in rather typical fashion on the love song".

"[7] An editor, Robbert Tilli, wrote, "With "I Believe" Detroit delivered the "perfect pop single" with the right eyecatching artwork, showing her with a Philip Tracey-designed glove-shaped hat, as if the muse herself is putting her supportive hand on her head.

In 2005, German singer Joana Zimmer covered the song and released it as "I Believe (Give a Little Bit)" on Polydor Records as her debut single.
