The Isle of Wight, an island off the south coast of England, was part of the historic county of Hampshire (originally Southamptonshire), and was linked with it for parliamentary purposes until 1832, when it became a county constituency in its own right as it had also been during the Protectorate (1654–1659). Hampshire (including the Isle of Wight), located in the 21st century region of South East England, was represented in Parliament from the 13th century. This article provides a list of constituencies constituting the Parliamentary representation from Isle of Wight.

In 1890 the Isle of Wight became an administrative county. In 1974 it became a new non-metropolitan county and in 1995 a ceremonial county and unitary authority (with unchanged boundaries).

The first part of this article covers the constituencies wholly within the area of the Isle of Wight. The second part refers to the constituency of Hampshire, which included some territory from the Isle of Wight 1290–1654 and 1659–1832. The summaries section only refers to the constituencies included in the first section of the constituency list.

Article names are followed by (UK Parliament constituency). The constituencies which existed in 1707 were those previously represented in the Parliament of England.
