In philosophy, empiricism is an epistemological view which holds that true knowledge or justification comes only or primarily from sensory experience and empirical evidence. It is one of several competing views within epistemology, along with rationalism and skepticism. Empiricists argue that empiricism is a more reliable method of finding the truth than purely using logical reasoning, because humans have cognitive biases and limitations which lead to errors of judgement. Empiricism emphasizes the central role of empirical evidence in the formation of ideas, rather than innate ideas or traditions. Empiricists may argue that traditions arise due to relations of previous sensory experiences.

इंद्रियानुभववाद या अनुभववाद (एंपिरिसिज्म) एक दार्शनिक सिद्धान्त है जिसमें इंद्रियों को ज्ञान का माध्यम माना जाता है। इंद्रियानुभववाद के अनुसार, इंद्रियों से प्राप्त होने वाला अनुभव अथवा किसी भी रूप में होने वाला अनुभव ही ज्ञान का और हमारे संप्रत्ययों (concepts) का एकमात्र अंतिम आधार है।
