Annealing may refer to:

  • Annealing (metallurgy), a heat treatment that alters the microstructure of a material causing changes in properties such as strength, hardness, and ductility
  • Annealing (glass), heating a piece of glass to remove stress
  • Nucleic acid thermodynamics, includes the annealing of DNA or RNA pairing by hydrogen bonds to a complementary sequence, forming a double-stranded polynucleotide
  • Simulated annealing, a technique for searching for a solution in a space otherwise too large for ordinary search methods to yield results
  • Quantum annealing, a method for finding solutions to combinatorial optimisation problems and ground states of glassy systems using quantum fluctuations
