The protest will start in Kirkcaldy with a mass 'die in'.
There's a demonstration in Kirkcaldy's Town Square today, protesting at British bombing in Syria.
MPs voted in favour of increased airstrikes in the Middle East earlier this month. Bombing was already taking place on so called Islamic State targets in Iraq.
The march will take place in Kirkcaldy town centre at around 1.00 pm.
The group, called Fife Against The War, does not believe the bombing campaign will make the UK safer, and claims it will put us at greater risk of terrorist attack.
It claims 70% of Scots are against the action, and are calling for the UK Government to spend the money on combating poverty instead.
