A review is presented of mathematical methods and results concerning non- archimedean quantum theory. It is assumed that the wave functions are defined over the non-archimedean space and take their values in non- archimedean fields. The models of nonarchimedean quantum mechanics, field theory and string theory are considered. The counterparts of Bargmann as well as Schrödinger representations are constructed. The existence and uniqueness theorems for the Schrödinger, Heisenberg and Liouville equation are proven. Non-archimedean scalar boson field is quantized with the help of Feynman path integrals. The non-archimedean counterpart of Klein-Gordon equation is investigated. It is shown that within this framework a new characteristic of electron arises, the so called non- archimedean color. Finally, a non-archimedean bosonic string theory is quantized in the light cone.
