Dozens of events will be held across the region, with up to 8,000 expected at Weston Park on Sunday alone.
In Oswestry, the annual bonfire and fireworks display will take place on Saturday, from 6pm, at Brogyntyn Park.
The event, organised by Oswestry Town Council and the Treble Niners, is now into its second decade and has raised more than £40,000 for good causes. Extra fireworks have been bought for this year and organisers have promised the biggest display in memory. Entrance is £5 for adults and £1 for children. John Davies, leader of the Treble Niners, said "The atmosphere is always most enjoyable and, by bringing the community together, we help raise funds for good causes and those less fortunate."
A huge firework display provided by the same firm responsible for displays at the Olympic Games and London's New Year celebrations will take place in Shrewsbury.
