约翰·戈特利布·费希特（德语：Johann Gottlieb Fichte，1762年5月19日－1814年1月27日），德国哲学家。尽管他是自康德的著作发展开来的德国唯心主义哲学的主要奠基人之一，但他在西方哲学史上的重要性往往被轻视了。费希特往往被认为是连接康德和黑格尔两人哲学间的过渡人物。近些年来，由于学者们注意到他对自我意识的深刻理解而重新认识到他的地位。和在他之前的笛卡尔和康德一样，对于主观性和意识的问题激发了他的许多哲学思考。费希特也涉及政治哲学，他被一些人认为是德国国家主义之父。

Johann Gottlieb Fichte (/ˈfɪxtə/; German:[ˈjoːhan ˈɡɔtliːp ˈfɪçtə]; May 19, 1762 – January 27, 1814), a German philosopher, became a founding figure of the philosophical movement known as German idealism, which developed from the theoretical and ethical writings of Immanuel Kant. Recently, philosophers and scholars have begun to appreciate Fichte as an important philosopher in his own right due to his original insights into the nature of self-consciousness or self-awareness. Fichte was also the originator of thesis–antithesis–synthesis (Thesis–Antithesis–Synthesis), an idea that is often erroneously attributed to Hegel. Like Descartes and Kant before him, Fichte was motivated by the problem of subjectivity and consciousness. Fichte also wrote works of political philosophy; he has a reputation as one of the fathers of German nationalism.
