Phosphorus-32 (32P) is a radioactive isotope of phosphorus, containing one more neutron than the common and stable isotope of phosphorus, phosphorus-31.

Phosphorus is found in many organic molecules, and so, phosphorus-32 has many applications in medicine, biochemistry, and molecular biology where it can be used to trace phosphorylated molecules (for example, in elucidating metabolic pathways) and radioactively label DNA and RNA.
