Activists gathered in Kelvingrove park from around 10am on Saturday with many singing and chanting in the pouring rain for hours.
Between 50,000 and 100,000 people are estimated to join in the protests with crowds descending on Glasgow Green at around 3pm.
Here is a selection of images from the protests so far.
