Abstract
The purpose of this paper is to introduce and to discuss the concept of orthogonality in the locally convex spaces, and obtaining some results on orthogonality in locally convex spaces similar to orthogonality of normed spaces. We shall obtain some characterizations of the best approximation and the best coapproximation in locally convex spaces.
