Danish philosophy has a long tradition as part of Western philosophy.

Perhaps the most influential Danish philosopher was Søren Kierkegaard, the creator of Christian existentialism, which inspired the philosophical movement of Existentialism. Kierkegaard had a few Danish followers, including Harald Høffding, who later in his life moved on to join the movement of positivism. Among Kierkegaard's other followers include Jean-Paul Sartre who was impressed with Kierkegaard's views on the individual, and Rollo May, who helped create humanistic psychology.

Current developments and events in the Danish philosophical community are continuously reported on the blog Philosophy in Denmark.

Søren Aabye Kierkegaard (/ˈsɔrən ˈkɪərkəɡɑrd/ or /ˈkɪərkəɡɔr/; Danish: [ˈsɶːɐn ˈkiɐ̯ɡəɡɒːˀ] ( listen)) (5 May 1813 – 11 November 1855) was a Danish philosopher, theologian and religious author. He was a critic of idealist intellectuals and philosophers of his time, such as Georg Wilhelm Friedrich Hegel, Friedrich Wilhelm Joseph Schelling and Karl Wilhelm Friedrich Schlegel. He was also critical of the state and practice of Christianity, primarily that of the Church of Denmark. He is widely considered to be the first existentialist philosopher.

Much of his philosophical work deals with the issues of how one lives as a "single individual", giving priority to concrete human reality over abstract thinking, and highlighting the importance of personal choice and commitment.

His theological work focuses on Christian ethics, on the institution of the Church, and on the differences between purely objective proofs of Christianity. He wrote of the individual's subjective relationship to Jesus Christ, the God-Man, which came through faith. Much of his work deals with the art of Christian love.
