Yes there are a few brands of low calorie and/or low sugar jams and jellies. To add to the confusion, they're often labeled "fruit spread," rather than jelly or jam.
I've had this brand and it's really good

Smucker's is another brand that's very popular, and in addition to regular jams and jellies they also have sugar-free versions (hubby is a big fan of grape jelly, and he's diabetic so we buy the Smucker's sugar free grape jelly quite often).
Aldi stores (I know Aldi stores are in other countries, but I don't know if the products are the same) carries a "Fit and Active" brand of no-sugar-added jams. I like the strawberry and the black currant. The have a couple other flavors, but I don't remember them off-hand. I think one is a mixed fruit combo called "fruits of the forest."
I also googled and found this little article that was interesting

The one good thing about American's being so food obsessed, is that we can get almost any food available anywhere in the world. I've become addicted to gourmet import shops and asian markets. Exotic fruits are my favorite, and I'll spend ridiculous prices to try a fruit I've never had before. I spent more than $5 to try a dragonfruit. It was very pretty and tasted nice, but not special enough to ever buy one again.
