The land which became Quarryville Borough was originally located within Providence Township and was the property of a John ("Swamp John") Groff. There was a stone quarry adjacent to the village where many of the workers lived. This village became larger as the work force grew, hence the town acquired the name "Quarryville". Locals say that one day the men went to lunch and returned to find the quarry half-full of water. The quarry site remains, now full of water.

Every September, the community is home to the Solanco Fair, which began in 1950 and takes place on the Solanco Fairgrounds.

The final scenes in the movie The Boys from Brazil (film) take place on a farm near Quarryville.
