• Lattice model (physics), a physical model that is defined on a periodic structure with a repeating elemental unit pattern, as opposed to the continuum of space or spacetime.

• Lattice model (finance), a "discrete-time" model of the varying price over time of the underlying financial instrument, during the life of the insturment.

• Lattice model (mathematics), a regular tiling of a space by a primitive cell.

• Lattice model (computational biology), equivalent to Markov chains formulated e.g. with the help of Hidden Markov Models.

• Lattice model (biophysics), a class of Ising-type models for the description of biomacromolecules, their transformations and binding in gene regulation and signal transduction.
