Antimon (₅₁Sb) yang terbentuk secara alami terdiri dari dua isotop stabil, ¹²¹Sb dan ¹²³Sb. Ada 35 isotop radioaktif buatan, yang paling lama berumur ¹²⁵Sb, dengan waktu paruh 2,75856 tahun; ¹²⁴Sb, dengan waktu paruh 60,2 hari; dan ¹²⁶Sb, dengan waktu paruh 12,35 hari. Semua isotop lain memiliki waktu paruh kurang dari 4 hari, kebanyakan kurang dari satu jam. Unsur ini juga memiliki banyak isomer, yang berumur paling panjang adalah ^120m1Sb dengan waktu paruh 5,76 hari.
