ABSTRACT=<p>In this article, first, we give the definition of normal curves in 4-dimensional Galilean space <italic>G</italic><sup>4</sup>. Second, we state the necessary condition for a curve of curvatures τ(<italic>s</italic>) and σ(<italic>s</italic>) to be a normal curve in 4-dimensional Galilean space <italic>G</italic><sup>4</sup>. Finally, we give some characterizations of normal curves with constant curvatures in <italic>G</italic><sup>4</sup>.</p>
