In mathematics, a tensor is an algebraic object that describes a multilinear relationship between sets of algebraic objects related to a vector space. Tensors may map between different objects such as vectors, scalars, and even other tensors. There are many types of tensors, including scalars and vectors, dual vectors, multilinear maps between vector spaces, and even some operations such as the dot product. Tensors are defined independent of any basis, although they are often referred to by their components in a basis related to a particular coordinate system; those components form an array, which can be thought of as a high-dimensional matrix.

प्रदिश या टेंसर (Tensors) वे ज्यामितीय वस्तुएं हैं जो सदिशों, अदिशों तथा प्रदिशों के बीच रैखिक सम्बन्ध बताती हैं। अदिश गुणनफल, सदिश गुणनफल, रैखिक चित्रण आदि प्रदिश के कुछ सरल उदाहरण हैं। सदिश और अदिश स्वयं प्रदिश हैं। प्रदिश को संख्यात्मक मानों की बहुआयामी अर्रे द्वारा निरूपित किया जा सकता है।
