Not an oak... oaks have alternate leaves with lobed, but not divided,
leaf blades.

Not poison ivy... PI has alternate leaves also, trifoliolate, with a stalked
central leaflet.

Possibly an ash seedling, though most species have young leaves with 5-7
leaflets instead of just three. Leaves are opposite in most species.

Most likely a box elder seedling, Acer negundo -- youngest leaves are often
trifoliolate, with a central stalked petiole, but leaves are opposite
and what I see of the petiole looks good for A. negundo. Here's a
nice series of photos:

Check the petiole base shape on your seedling vs. the ash you mention and
the photos of A. negundo. Also pull off a leaf (not a leaflet) and check
the patterns of the main veins leading into the stem -- in the fall, these
will be the "dots" inside the leaf scar.

Where was the photo taken?
