Absolutely, both are very complimentary to one another.
You spend some time in both doing the same techniques even, there is just a greater concentration on takedowns/throws in Judo than there is in BJJ. And there is a greater concentration on ground work (chokes, joint locks from the ground) in BJJ.
Many many people cross train in both because each art helps them to become a better grappler as a whole.
