Christa Marion Ackroyd is an English journalist and broadcaster, best known as a former presenter for the regional TV news programmes Calendar (for Yorkshire Television) and BBC Look North.

Ackroyd was born and educated in Bradford; her father was a policeman.

After leaving school, Ackroyd spent four years working for the Halifax Courier. She began her broadcasting career in the newsroom of commercial radio station Pennine Radio in Bradford (now The Pulse of West Yorkshire), where she led the station's coverage of the Yorkshire Ripper case.

In 1981, she moved to neighbouring Radio Aire in Leeds, reading its first news bulletin on its opening day. In November 1982, she was appointed as the UK's first female radio news editor. Ackroyd was promoted as Radio Aire's programming controller in 1985, often presenting weekend shows and the station's flagship news programme, Radio Aire Reports.

In 2014, Ackroyd was made patron of Radio Aire's Cash for Kids charity.

Ackroyd switched to television in 1990 and became a co-anchor for Yorkshire Television's regional news programme Calendar, originally alongside Richard Whiteley, and later, Mike Morris. In September 2001, she switched to the BBC to present the Leeds-based edition of Look North with Harry Gration.

While working at Yorkshire Television and the BBC, Ackroyd also wrote a weekly column for the Sunday Express. In 2004, she refused to give up the column following a BBC request amid concerns over impartiality. She resigned from the paper in January 2007.

Ackroyd presented her last Look North programme on 1 March 2013. Several weeks later, a Yorkshire Post article questioned her absence from the programme and whether her salary, reported to be around £150,000 per year, was justified. The BBC declined to explain her prolonged absence, citing unspecified "editorial reasons". Shipley MP Philip Davies called for the corporation to explain whether Ackroyd was still being paid despite her ongoing absence.
