Piershil is a village in the Dutch province of South Holland.

It is a part of the municipality of Hoeksche Waard, and lies about 5 km south of Spijkenisse.

The village was first mentioned in 1452 as "vidimus Piershille", and means "hill of Pier (diminutive of Pieter)".

The area was poldered in 1246, but lost in 1421 or 1479 and repoldered in 1524.

The northern wing was added in 1642, and redeveloped into a consistory between 1970 and 1971.
