Oxygen demand is an environmental chemistry term that may refer to:

  • Biochemical oxygen demand (BOD), the amount of oxygen needed by organisms to break down organic material present in a water sample
  • Carbonaceous biochemical oxygen demand (CBOD), the amount of oxygen needed to break down carbon compounds, excluding nitrogen compounds
  • Chemical and biological oxygen demand, the combination of biochemical (BOD) and chemical oxygen demand (COD)
  • Chemical oxygen demand (COD), a test commonly used to indirectly measure the amount of organic compounds in a water sample
  • Nitrogenous oxygen demand (NOD), the amount of oxygen required to break down nitrogenous compounds in a water sample, like ammonia
  • Theoretical oxygen demand (ThOD), the calculated amount of oxygen required to oxidize a compound to its final oxidation products
