Not really, I mean I've named a couple of things, but I don't have a habit of doing so, although I think it's awesome when people do name their things.
Apart from the regular type of things I named as a kid, like dolls, stuffed animals and horse-figures (and I had their relationships with one another all figured out as well, but I can't remember all the names now), I've only named a couple of things as an adult.
I have an animatronic monkey who I bring with me to every convention I go to, who I named Simon. He's been with me for almost nine years and I consider him my "baby" (my parents even joke that he's their fifth grandchild - although I keep pointing out that technically he's the third, since I got him when my second niece was baby). I also have a dragon figurine with a large coffee cup that I named Lorelai (after the coffee-addicted character in Gilmore Girls), it just made complete sense that this dragon had that name. And mom and I once named one of our Christmas trees. It was the tiniest tree we had ever had in the house, so of course the name became "Pinglus the great" (it's a play on a Norwegian slang word that refers to something being smaller than normal).
I can't think of anything else I've named, although I have plenty of things worthy of names.
