Can someone tell me what this thorny item is?

looks like a Blackberry briar vine

In Texas we call them dewberries, they are small blackberries that grow wild especially along pasture fences.

My family loves eating these blackberries, but they are an invasive weed and difficult to eradicate!

Looks like raspberry bush.

They are mulberry bushes and the berries are delicious

this just showed up this year on the side of our shed. There is a mulberry tree hanging over into our property from our neighbors side all the way on the other side of yard (half acre). It's not thorny like this. This is also about 3 feet and growing really fast. Also, the neighbor to the right has woods which separate us. So it has a lot of wild items in there that we have to keep from coming over here. My husband decided this year no chemicals. so, we are seeing deer and other critters because we have a lot of plant items we dont want to cut/kill until we know for sure it's a weed. Like this. And strawberry looking plants with purple or yellow flowers.

I have the same in my yard with no berries, just flowers. I believe it's wild roses.

It's a blackberry or possibly a raspberry, but it's hard to tell in the photo. Raspberries have a red briar 'fuzz' along the stems.

it looks like raspberries!

they flower first and then fruit

Raspberry plant

No flowers. Not yet. I will keep watching. But it's new. It just showed up. it wasn't there last year.

Ok. Look what I found just now. I am thinking its trying to take contro!!

its all on the side of the shed. Its everywhere!

The answers are all close but not quite. They are called wineberries, Rubus phoenicolasius, and are invasive, but also so delicious I always let them get a little out of control in my yard. Like a perfect sweet raspberry with less seeds. They do not store well, so you rarely see them sold, but you will eat them so quickly storage doesn't matter. Also great for jams, pies, cobblers, and if course, wine.

Wineberry. a.k.a Rubus Phoenicolasius

Let it grow to dee if it is worth saving for the fruit or get rid if you don't like it - the choice is yours.

Looks like a typical blackberry plant in Oregon. Here they are invasive and take over then acreas of land.
