Assuming 2.79: it only exists in Object mode.
Select this mode from the header/footer of the Viewport (or, if you are in Edit mode, just hit Tab)
If you are using Blender 2.80+ and following a <2.79 tutorial, then most of the transforms that used to be under Tools > Edit are now in the header of the Viewport under "Object".
