Unite Against Fascism will mark UN anti-racism day on Saturday with a march from Riverside to City Hall to protest against discrimination.
Between 500 and 1,000 people are expected to take part in the march which is supported by a number of trade unions including Unite, GMB and Unison and will leave Clare Gardens at 11am.
Jeff Hurford, secretary of United Against Fascism Wales, said the march is aiming to stop immigrants being blamed for problems in the UK.
He said: “It is to raise awareness of discrimination, especially because we are seeing now, and have seen for the past few months, a return of racism in politics.
“But most of the issues people are blaming immigrants for are nothing to do with immigrants. There is a lack of jobs and there are not enough houses being built, these are problems we see in countries even without a large immigrant population.
“I am marching to defend my way of life, which is a multicultural way of life.”
A number of members of The People’s Assembly will be attending the march and Rob Griffiths, a spokesman for the group, said speaking up against discrimination was particularly important in the age of austerity.
He said: “Part of the government’s strategy when driving through austerity measures is to identify scapegoats and divert attention away from the economic crisis.
“But in Cardiff we have a long history of being a multicultural society which makes us more determined to stop this from happening.”
Riverside Councillor Cecilia Love said: “Demonstrations are also being held in Glasgow and London, with Diane Abbot and Green Party leader Natalie Bennett among the speakers in the English capital.”
