Spin states analogous to the coherent states of the linear harmonic oscillator are defined and their properties discussed. They are used to discuss some simple problems (a single spin in a field, a spin wave, two spin 1/2 particles with Heisenberg coupling) and it is shown that their use may often give increased physical insight.
