William Alexander Hay, Baron Hay of Ballyore (born 16 April 1950), is a Democratic Unionist Party (DUP) politician, serving as a life peer in the House of Lords since 2014.

Hay served as Speaker of the Northern Ireland Assembly from 2007 to 2014, as well as a Member of the Northern Ireland Assembly (MLA) for Foyle from 1998 to 2014.

He attended Faughan Valley High School, Drumahoe, County Londonderry. An Irish citizen by birth, he has objected to previously not being deemed automatically eligible for British nationality.^[2] This policy is due to be changed in 2024

Hay was elected to Londonderry City Council in Northern Ireland in 1981 for the Democratic Unionist Party. He served as Mayor in 1993 and Deputy Mayor in 1992. In 1996 he was an unsuccessful candidate in the Northern Ireland Forum election in Foyle.,^[3] but was elected to the Northern Ireland Assembly in 1998. He is a member of the Northern Ireland Housing Council and the Londonderry Port and Harbour Commission.^[4] and in 2001 became a member of the Northern Ireland Policing Board.

Hay was elected Speaker of the Northern Ireland Assembly on 8 May 2007 following the restoration of devolution. He also is a prominent member of the Orange Order^[5] and Apprentice Boys of Derry.

On 6 October 2014, Hay announced his retirement from the Northern Ireland Assembly as both MLA and Speaker. The role of the Speaker had been taken on by Mitchel McLaughlin in a temporary capacity in September 2014 because of Hay's ill health. However, in a letter read to the Assembly, he announced his retirement from the Assembly effective from 13 October 2014 in order to concentrate on returning to good health.^[6][7][8]

In August 2014, it was announced that he would get a life peerage to sit in the House of Lords and he opted to sit there as a crossbencher, despite being nominated by DUP.^[9] Hay was ennobled on 16 December 2014 and took the title Baron Hay of Ballyore, of Ballyore in the City of Londonderry.^[10] He subsequently sat as a DUP member.^[11]

Hay was born in Milford in the north of County Donegal in the north-west of Ulster in 1950.^[12][13] County Donegal, the largest county in Ulster, is one of the three counties in Ulster that is part of the Republic of Ireland; the other six counties in Ulster make up Northern Ireland. At the age of six, Hay moved with his family to Derry.^[12] He is an Irish citizen with an Irish passport because he refuses to pay a £1,300 UK naturalisation fee (and take the "Life in the UK" test) required for people, such as him, who were born in the Republic of Ireland but who wish to become a British citizen.^[14] "I see myself as a British citizen living in Northern Ireland all my life. I have a right to British citizenship and a British passport. I am being discriminated against because I can't get my British passport," he told the Northern Ireland Affairs Committee at Westminster in April 2021.^[15] In January 2024, a Private Members Bill brought forward by Gavin Robinson passed, allowing people born in the Republic of Ireland after 1948 that have been living in Northern Ireland for longer than 5 years to register as British citizens. It is not known when the bill will become law.^[16]
