客观性是哲学的一个中心概念，指一个事物不受主观思想或意识影响而独立存在的性质，跟「主观性」相对应。客观的事实，不受人的思想、感觉、工具、计算等主观手段的影响，而能保持其真实性。

Objectivity is a central philosophical concept, related to reality and truth, which has been variously defined by sources. Generally, objectivity means the state or quality of being true even outside of a subject's individual biases, interpretations, feelings, and imaginings. A proposition is generally considered objectively true (to have objective truth) when its truth conditions are met without biases caused by feelings, ideas, opinions, etc., of a sentient subject. A second, broader meaning of the term refers to the ability in any context to judge fairly, without partiality or external influence. This second meaning of objectivity is sometimes used synonymously with neutrality.
