"Shake It Up Tonight" is a song by American singer Cheryl Lynn. Since the success of her debut single, "Got to Be Real", the acclaimed R&B-dance track peaked at No. 5 on both the R&B and Hot Dance Club Play charts, and it also scored number 70 on the Billboard pop charts. It failed to chart in the UK.

"Shake It Up Tonight" appears on Lynn's LP In the Night, and was written by Mike and Brenda Sutton. The B-side is "Baby", written by Cheryl Lynn and Ray Parker Jr. The ready-made disco song was a moderate success. It became a defining song for Lynn. The 7" version of the song was recorded and produced by Ray Parker Jr. who has worked with her. Jamaican singer Luciano covered the song as a number-one reggae hit in 1993. The 12" version was mixed and produced by Ray Parker Jr.
