Newport East (Welsh: Dwyrain Casnewydd) is a constituency^{[n 1]} in the city of Newport, South Wales, represented in the House of Commons of the UK Parliament since 2005 by Jessica Morden of the Labour Party.^{[n 2]}

The constituency is to retain its name but its boundaries altered, as part of the 2023 Periodic Review of Westminster constituencies and under the June 2023 final recommendations of the Boundary Commission for Wales for the next United Kingdom general election.^[3]

1983–1997: The Borough of Newport wards 2, 4, 7, 9, 11, 13, and 18 to 20, and the District of Monmouth wards 14 and 15.

1997–2010: The Borough of Newport wards of Alway, Beechwood, Langstone, Liswerry, Llanwern, Ringland, St Julian's, and Victoria, and the Borough of Monmouth wards of Caldicot Castle, Dewstow, Magor with Undy, Rogiet, Severn, and West End.

2010–present: The Newport County Borough electoral divisions of Alway, Beechwood, Langstone, Liswerry, Llanwern, Ringland, St Julian's, and Victoria, and the Monmouthshire County electoral divisions of Caldicot Castle, Dewstow, Green Lane, Mill, Rogiet, Severn, The Elms, and West End.

Newport East was created when the former Newport borough constituency was split into two divisions in 1983. It also included some rural areas formerly part of Monmouth county constituency. There have been only minor boundary changes since the constituency was created, and unlike the neighbouring Newport West, has remained Labour since its creation.
