  Let $G$ be an algebraic group over a field $k$. We call $g\in G(k)$ {\bf
real} if $g$ is conjugate to $g^{-1}$ in $G(k)$. In this paper we study reality
for groups of type $G_2$ over fields of characteristic different from 2. Let
$G$ be such a group over $k$. We discuss reality for both semisimple and
unipotent elements. We show that a semisimple element in $G(k)$ is real if and
only if it is a product of two involutions in $G(k)$. Every unipotent element
in $G(k)$ is a product of two involutions in $G(k)$. We discuss reality for
$G_2$ over special fields and construct examples to show that reality fails for
semisimple elements in $G_2$ over $\Q$ and $\Q_p$. We show that semisimple
elements are real for $G_2$ over $k$ with $cd(k)\leq 1$. We conclude with
examples of nonreal elements in $G_2$ over $k$ finite, with characteristic $k$
not 2 or 3, which are not semisimple or unipotent.
