Janet Lee, currently editor of BBC One's flagship arts and culture strand, Imagine, presented by Alan Yentob, is moving over the BBC Two's The Culture Show.
Lee will work across both production bases in both London and Glasgow.
She takes over from Edward Morgan, who announced he was stepping down from The Culture Show in order to take up a post as head of the college of production at the BBC Academy.
Previously Lee was commissioning editor for arts at Channel Four.
Karen O'Connor, head of London factual said: ‘I am delighted Janet Lee is to be the new editor of The Culture Show. She brings great expertise and a fantastic contacts book to this role, which will help The Culture Show to further flourish.
‘I would also like to thank Eddie Morgan for his vibrant creative leadership over the past five years.'
The Culture Show is broadcast on Thursday nights at 7pm during each series. It was recently expanded to a 60-minute slot on BBC Two. The new series begins on 22 October with a programme from The London Film Festival.
