碲（原子量：127.60(3)）有39种同位素与17种同核异构体，原子量介于104至142。其中，有八种同位素（¹²⁰Te、¹²²Te、¹²³Te、¹²⁴Te、¹²⁵Te、¹²⁶Te、¹²⁸Te、¹³⁰Te）存在于自然界。¹²⁸Te和¹³⁰Te有放射性，但半衰期都极长，分别为2.25×10²⁴年和7.91×10²⁰年。碲最长寿的人造同位素则是半衰期19.31天的¹²¹Te，但诸如^121mTe（半衰期164.7天）的同核异构体有更长的半衰期。

放射性同位素¹²⁸Te和¹³⁰Te是碲最常见的两种同位素。碲与铟、铼一样都是放射性同位素的丰度比稳定同位素的丰度大的例子。

有团队报告称已发现¹²³Te的电子捕获，但他们之后的测量结果否认了这点。¹²³Te的半衰期至少为9.2×10¹⁶年。
