The Gaskiers Formation is a geologic formation in Newfoundland and Labrador, and takes its named from the wider Gaskiers-Point La Haye area.

The Gaskiers-Point La Haye/Gaskiers Formation gets its name to the Gaskiers glaciation, a glacial event that was around during a majority or short period of the formations range, [4] with recent evidence suggesting that the event actually started a lot earlier than was previously thought in the underlying Mall Bay Formation.
