Naturally occurring titanium (₂₂Ti) is composed of five stable isotopes; ⁴⁶Ti, ⁴⁷Ti, ⁴⁸Ti, ⁴⁹Ti and ⁵⁰Ti with ⁴⁸Ti being the most abundant (73.8% natural abundance). Twenty-one radioisotopes have been characterized, with the most stable being ⁴⁴Ti with a half-life of 60 years, ⁴⁵Ti with a half-life of 184.8 minutes, ⁵¹Ti with a half-life of 5.76 minutes, and ⁵²Ti with a half-life of 1.7 minutes. All of the remaining radioactive isotopes have half-lives that are less than 33 seconds, and the majority of these have half-lives that are less than half a second.^[4]

The isotopes of titanium range in atomic mass from 39.00 u (³⁹Ti) to 64.00 u (⁶⁴Ti). The primary decay mode for isotopes lighter than the stable isotopes (lighter than ⁴⁶Ti) is β⁺ and the primary mode for the heavier ones (heavier than ⁵⁰Ti) is β⁻; their respective decay products are scandium isotopes and the primary products after are vanadium isotopes.^[4]
