Die ARD ließ 1981 sechzehn Folgen der ersten Staffel synchronisieren. Die übrigen liefen erst ab 1992 auf RTL. Da RTL es sehr eilig hatte, wurde Quincy parallel von Hans-Werner Bussinger und Gerd Paul eingesprochen. Zur Folge 1x4 existieren zwei Synchronfassungen. Die ARD zeigte die 70-minütige Urfassung, RTL importierte die Syndication-Fassung und synchronisierte sie komplett neu. Auf der DVD ist die Langfassung enthalten.
