Is this poison ivy?

Hi... just wondered if anyone here has expertise on plants and would know if any of these ones under the porch and on the grass are poison ivy...and if not, what they are.

It's always hard for me to tell because there are a lot of three-leaf plants, and most generic pictures of poison ivy are fairly non-descript or so different from each other that it's always hard to tell.

Thanks!

As you said, number 1 and 3 look definite; number two not.

An informative question ... they all look so innocuous to to my untrained botanical eye

On close inspection (zooming up), only number 1 appears to be definte.

Number two photo 6232 is 100% not poison oak or poison ivy.
So, if you are the weed puller in the family go ahead, and no gloves needed.

The golden rule is beware plants with 3 leaves. And poison ivy can have berries.
The middle leaf will stick out more and almost always has a small stem.
The two side leaves grow directly from the vine and do not have small stems.
I was cleaning the yard and saw a few 3 leaf ones. I proceeded any way. Nothing for 3 days but on the 4th day here comes the irritation and a week of itching and discomfort.
If you wear gloves or use weed killer on all plants with 3 leaves you'll be ok.

As you can see from your photos, poison ivy likes to grow around something like a tree or a fence, and wrap  itself around as it grows.

Paul's photo clearly shows the center leaf having a stem and the other two do not.
That's it alright and it's a touch me not.

Thanks for all the feedback.  Looks as if I should assume the one under the porch is, but not the one on the grass.

Good, practical and safe, assumption.  :-)

One little postscript comment:  Afterwards, I found out that it's not poison ivy after all.  It's a boxelder plant (or it was, before I sprayed it).  They look almost the same except that with a boxelder, the leaf clusters are directly across from each other, whereas in poison ivy, they're staggered.
