Police are out in force after the English Defence League said it would hold a "meet and greet".
The event, which will also include leafleting, is due to start at 1.30pm in Kingston town centre.
A group of about 15 anti-fascist campaigners from Kingston and south-west London are handing out leaflets of their own.
Last November about 60 people marched from Hampton Wick to Kingston in a protest against poppy burning.
A small group of men attacked Kingston mosque later the same day.
