This is a list of transfers involving German football clubs during the 2020 summer transfer window. Only transfers of the Bundesliga and 2. Bundesliga are included. Due to the COVID-19 pandemic in Germany and the resulting impact on the scheduling of the 2019–20 and 2020–21 seasons, the German Football Association modified the dates for the summer transfer window. To allow for the registration of players based on previously signed contracts, the window opened on 1 July 2020 for a single day. The transfer window then re-opened on 15 July and closed on 5 October 2020.
