Speaking after the Dundee Together rally, local Trades Union Council chairman Hamish Drummond said the day was so successful that it might become an annual celebration.
"There's so much happiness with how today has gone. Dundee stood together, and saw hate out the door," he said.
The rally was supported by local politicians from across the parties, and by trade unions including Unison, Unite, PCS and the FBU.
Speaking to the rally, Jenny Marra, Labour MSP for North East Scotland, said: "Dundee is no place for racists. If the SDL truly knew this city they would know their message is not welcome here."
A wreath was also laid at Dundee's Spanish civil war memorial as part of the celebrations.
A very small number of SDL supporters attempted to hold a counter-demonstration - but retreated in humiliation.
