East Wicklow, a division of County Wicklow, was a parliamentary constituency in Ireland, represented in the Parliament of the United Kingdom. From 1885 to 1922 it returned one Member of Parliament (MP) to the House of Commons of the United Kingdom of Great Britain and Ireland.

Until the 1885 general election the area was part of the Wicklow constituency. From 1922 it was not represented in the UK Parliament, as it was no longer in the UK.

This constituency comprised the eastern part of County Wicklow. In 1918, the boundary of the constituency was expanded to include that part of the Bray urban district transferred from County Dublin to County Wicklow under the 1898 Local Government (Ireland) Act.

1885–1918: The baronies of Arklow, Newcastle and Rathdown, and that part of the barony of Ballinacor North contained within the parish of Calary.

1918–1922: The existing East Wicklow constituency, together with that part of the existing South Dublin constituency contained within the administrative county of Wicklow.
