The following are fictional characters in the American animated television series South Park.

Randy and Sharon Marsh are the most prominent set of parents on the show. Their first names are derived from the first names of series co-creator Trey Parker's parents. and Parker describes Randy as "the biggest dingbat in the entire show." Randy is voiced by Parker. Sharon was originally voiced by Mary Kay Bergman, later Eliza Schneider, and is currently voiced by April Stewart.

Shelly Lynn Marsh is Randy and Sharon's daughter and Stan's older sister. The character was voiced by Mary Kay Bergman until Bergman's death, and Shelly has subsequently been voiced by Eliza Schneider. Her new voice artist is April Stewart.

Shelly has an extremely aggressive temper and has very little respect for Stan and his friends, usually referring to them as "turds". In "An Elephant Makes Love to a Pig", she physically abused him, hurled him around their house, and in the feature film South Park: Bigger, Longer, Uncut, she demolished a wooden chair over his head. This does not mean she hates her brother, as in the former episode she lies to protect him from being sent away. There have been other moments when she also seems to have superhuman strength, and once had the ability to lift a piano over her head with ease, seen during "Mr. Hankey's Christmas Classics". She does help Stan when he is in real danger, although in "Pre-School" this was apparently only because she wants the privilege of beating up her brother all to herself.

In the episode "Cat Orgy", Shelly was dating Skyler, a 22-year-old who has his own band. Shelly also internet dated a boy named Amir in the episode "Over Logging" who she later met in California but could not properly look him in the eye.
