The first Scottish Greens co-leadership election occurred during the summer of 2019, following a newly adopted constitution by the party. One article of the constitution stated that the positions of co-conveners would be abolished in favour of the newly established positions of co-leaders. It also said that at least one of the co-leaders had to be a woman. Both of the former co-conveners, Maggie Chapman and Patrick Harvie, contested the election, but when the results were announced at the Out of Blue Drill Hall in Edinburgh on the 1st of August 2019, only Patrick Harvie was elected, alongside Lorna Slater. All Scottish Green Party members were eligible to vote.

Maggie Chapman is a Scottish politician and lecturer who is a Scottish Green Member of the Scottish Parliament (MSP) for North East Scotland. She was co-convenor of the Scottish Greens from November 2013 to August 2019, serving with Patrick Harvie, and was the party's lead candidate for the 2019 European election.
