1999/2000

Champions Cefn Druids were promoted to the League of Wales and were replaced by Holywell Town.

No teams were relegated from the Cymru Alliance, which had operated with sixteen teams in the previous term. Llangefni Town , winners of the Welsh Alliance, and Corwen Amateurs, Welsh National League (Wrexham Area) champions, joined the league on promotion. But the withdrawal of Mostyn on the eve of the campaign, after finishing bottom in 1998/99, saw the Cymru Alliance function with seventeen clubs.

Glantraeth led the way after completing the first half of their fixtures, from Welsh pool Town and Oswestry Town, although Llandudno, with a game in hand, posed a danger to the leading trio.

Unfortunately, the Bodorgan club were overwhelmed 5-0 by Northern Premier League outfit Colwyn Bay in the coast final. The Cymru Alliance flag reached the Third round of the Welsh Cup in 1998/99, with Llandudno and Rhydymwyn losing to Bangor City and Barry Town respectively, while Llangefni Town succumbed, on Anglesey , to Caerleon.

Oswestry Town were able to take their place in the League of Wales, after missing out five years earlier, and they replaced Caernarfon Town in the top flight.
