Non Serviam is a 1945 poetry collection by the Swedish writer Gunnar Ekelöf. The title comes from the Christian phrase "Non serviam", which is Latin for "I will not serve" and is attributed to Lucifer. In the poems Ekelöf criticises the contemporary political climate of Sweden; in the titular poem he describes himself as "a stranger in this land", and in the satirical poem "Till de folkhemske" he ironizes the concept of Folkhemmet.
