At least 200 people wearing yellow walked from Centennial Park to the Soundshell at Caroline Bay.
This is the second year Hope Walk has ran in Timaru, organised by a Timaru mum who lost her son to depression.
A mental health advocate and comedian, Mike King, gave a speech in the Soundshell after the walk to emphasise the importance of asking if you need help.
Solomon Taylor, who has lost three people to suicide in the last year, said the event "hit home" for him.
He said he walked because he wanted those suffering from depression to know there were always people they could talk to.
