The 2020 Tour de Wallonie (known as the VOO–Tour de Wallonie for sponsorship reasons) was a four-stage men's professional road cycling race mainly held in the Belgian region of Wallonia.

It was the forty-seventh edition of the Tour de Wallonie, starting on 16 August in Soignies and finishing on 19 August in Érezée.

It was originally scheduled for 27 – 31 July, but due to the COVID-19 pandemic, it was postponed to mid-August after the UCI's May calendar update and was shortened from five stages like in years prior to four stages.

Each team entered seven riders, with the exception of Israel Start-Up Nation, which only entered six.

123 of the 153 riders that started the race finished.
