Beckham is one of 30 big names in fashion to take part in the campaign.
The campaign is being curated by Love magazine editor Katie Grand and includes names such as Prada, Burberry and Paul Smith.
Beckham's design of the famous mascot is a beige leather lady teddy wearing a brown dress. The bear has a red pout and a silk ribbon eye patch.
The collection will go on display in the Selfridges stores in London and Manchester until November 14. After this they will be auctioned off to raise money for Christie's.
Curator Katie Grand said: "I was honoured to curate this fantastic collection, and have had such fun working with the designers on all of their amazing designs.
''BBC Children in Need is an incredibly worthwhile cause, and one which myself and all of the designers involved in the collection are privileged to support.''
Selfridges creative director Alannah Weston said the company was pleased to be getting involved in such a ''creative project''.
She added: ''Selfridges is delighted to support such a purposeful and creative project. It is wonderful to see such remarkable talent helping this most worth cause.''
