The top UK art fair is probably the London Art Fair. This has over 100 galleries and is attended by viewers, buyers, critics and media people from all over the world. The next one will take place in January 2013.

However, there are Art Fairs all over the UK and you can probably find one near you if you put 'art fair' plus your nearest city name in a search engine. Brighton also has a major fair - it will be held in September this year - and if you are looking for something different you could try the Affordable Art Fair, a less formal but exciting event also held in London. This year's fair is at Battersea from 15 March, so you will have to hurry if you want to catch it!

You could also try looking at specialist sites such as artforum, which lists art events held in different international cities, and includes other important UK events.
