The 2020 Collingwood Magpies season was the club's fourth year of senior competition in the Suncorp Super Netball league. The club would have fielded a reserves team in the Australian Netball League, though were prevented from doing so due to the COVID-19 pandemic. The Magpies were coached by Rob Wright and co-captained for the second consecutive year by Geva Mentor and Madison Browne. The club entered the season off the back of a fourth-place finish and elimination final defeat in the 2019 season.
