放射性トレーサー（ほうしゃせいトレーサー、英: radioactive tracer, radiotracer）は、放射性標識（ほうしゃせいひょうしき、英: radioactive label）とも呼ばれ、1つまたは複数の原子が放射性核種に置き換えられた化学物質である。その放射性崩壊を利用して、反応物から生成物に至る経路を追跡することにより、化学反応の機構を調査するために使用することができる。放射性標識（英: radiolabeling）や放射性追跡（英: radiotracing）という手法は、同位体標識法（英: isotopic labeling）の放射性形態である。生物学的な分野では、放射性同位体トレーサーの使用は、放射性同位元素投与実験（英: radioisotope feeding experiments）と呼ばれることもある。

Gamma emitters, such as 46Sc, 140La, 56Mn, 24Na, 124Sb, 192Ir, 99Tcm, 131I, 110Agm, 41Ar and 133Xe are used extensively because of the ease with which they can be identified and measured. ... In order to aid the detection of any spillage of solutions of the 'soft' beta emitters, they are sometimes spiked with a short half-life gamma emitter such as 82Br...”
