Britt Allcroft (born Britney Allcroft in Johannesburg, South Africa) was co-founder of The Britt Allcroft Company with then-husband Angus Wright, known as Britt Allcroft Limited (later replaced as Gullane Entertainment) which was sold & acquired by HIT Entertainment in 2002. Allcroft is well known for her creation of the children's television series Thomas the Tank Engine & Friends and its US counterpart Shining Time Station. She was also the screenwriter and director of the motion picture Thomas and the Magic Railroad. She further created the TV show Magic Adventures of Mumfie, which is a show about a magical elephant.

In May of 2000 Allcroft was a director and advisor of Gullane but by 2003 (a year after Gullane was sold & acquired by HIT), Allcroft had resigned from her remaining positions with the company. This was attributed to the poor reception of Thomas and the Magic Railroad

She is currently working on a new live-action kids show called The Scoobs.
