Christine Chapman (born 7 April 1956) is a Welsh Labour Co-operative politician who was a Member of the National Assembly for Wales for Cynon Valley from 1999 to 2016.

Chapman has not held senior government posts and has been described in the Assembly Handbook as "one of the quietest women AMs ... [whose] effectiveness lies in her quiet willingness to discuss".

[5] In an interview from 2014, she attributed her politicisation to her feminist views, an aspiration to "make a difference" and her "anger" at an encounter with an "arrogant" local councillor who spoke down to her during her time as a careers adviser.

[3][9] In the first election to the new local authority of Rhondda Cynon Taf County Borough Council in 1995, Chapman stood as the Labour candidate for the electoral ward of Ynysybwyl.

Her main opponent was former ward councillor Gernant Jones of Plaid Cymru, who ran on a platform of prioritising the needs of the young and the elderly.

[3] In Rhondda Cynon Taf County Borough Council, Chapman served as the vice-chair of the Community Development and Libraries Sub-Committee from 1995 to 1998.

[13][17] On her selection, she said her priorities if elected to the assembly would be to improve local communities by addressing the causes of deprivation and poverty, which she said had been "fostered" by the 18 years of UK governance under the Conservative Party from 1979 to 1997.

[20] She was re-elected again in the 2007 assembly election with 11,058 votes, this time on a decreased majority of 5,623 over Plaid Cymru candidate Liz Walters,[21] and again in the 2011 assembly election with 11,626 votes, this time on an increased majority of 6,515 over the Plaid Cymru candidate Dafydd Trystan Davies.

[22] In the National Assembly for Wales, Chapman took an interest in the policy areas of education, training, social exclusion and equal opportunities.

[24][25] From 2000 to 2004, she chaired the Objective One Programme Monitoring Committee,[26] finding the time to complete an MPhil degree at Cardiff University in June 2001.

[3] In an article from 2020, Chapman revealed that she previously had bulimia nervosa since the age of 15, but that she had undergone successful therapy to treat the disorder since 2016.
