This article present the thought of Ludwig Wittgenstein about the conception of God. The main objective of this article is to present an attempt to describe Wittgenstein's thought, related to the concepts developed in his Tractatus Logico-Philosophicus and the Philosophical Investigations. This study contains a historical philosophical approach, with the aim of identifying Wittgenstein's conception of thinking about the subject and mystic, in which his concept of God takes place. In his attempt to present the concept of God, Wittgenstein approached through the philosophy of language. In the Tractatus, the philosopher deduces that everything that is thought must also be able to be spoken in the context of language as an expression of thoughts. But there are things that cannot be thought or said. It is beyond the borders of thought and language. This is what in the Tractatus is known as mystique, as something that can only be shown and cannot be talked about.
