Britain's Next Top Model, Cycle 4 is the fourth cycle of Britain's Next Top Model. The cycle, like the previous cycles, was aired on SkyLiving. The cycle was said to be "Bigger, better and bustier than ever before."

There were major changes in this cycle. The winner's prize changed and the judging panel also received a change; Icelandic fashion photographer Huggy Ragnarsson and Gerry Deveaux replaced two of the former judges, Paula Hamilton and Jonathan Phang.

This is the only cycle to feature a cast of 14 contestants until Cycle 6, rather than the usual 12 or 13. The international destination during this cycle was South Africa. The winner's prize was a contract with Models 1, an Revlon Comestics campaign, with a 6 page spread and cover of Company Magazine.

The winner was 18-year-old Alex Evans from Cranleigh, Surrey.
