Gibshill (sometimes spelt as Gibbshill and often referred to as The Gibby, but also known as Spam Island) is the easternmost housing estate in Greenock and adjoins Port Glasgow, both in the Inverclyde Council Area, Scotland.

This has changed "the Gibby" from a mainly working class area to a middle class suburb of Greenock with private housing making up two thirds the housing stock.

Large expanses of grass exist where housing once stood.

New housing, both council-owned and private sector, is planned to regenerate the area with some already built in Cobham Street, Bell Street (both private) and Shankland Grove (council-owned).

Wildlife is now common in the area with many rabbits and deer coming from the nearby moors.
