South Wales East was a European Parliament constituency covering south eastern Wales, including Gwent and parts of Mid Glamorgan.
Prior to its uniform adoption of proportional representation in 1999, the United Kingdom used first-past-the-post for the European elections in England, Scotland and Wales. The European Parliament constituencies used under that system were smaller than the later regional constituencies and only had one Member of the European Parliament each.
When it was created in Wales in 1984, it consisted of the Westminster Parliament constituencies of Blaenau Gwent, Caerphilly, Cynon Valley, Islwyn, Merthyr Tydfil and Rhymney, Monmouth, Newport East, Newport West, Rhondda, and Torfaen. The Cynon Valley moved to South Wales Central in 1994, leaving South Wales East with Blaenau Gwent, Caerphilly, Islwyn, Merthyr Tydfil and Rhymney, Monmouth, Newport East, Newport West and Torfaen.
The constituency replaced the similarly named South East Wales in 1984 and became part of the much larger Wales constituency in 1999.
