Easily-confused when 🌱︎ young (👟︎ ankle- to 🦵 knee-high)! Identification information from MSU, poison ivy quiz.
If each leaf contains:	with lateral (side) leaflets:	and terminal (end) leaflet:	and your specimen has/is a:	then you have:

5 leaflets	—	—	trailing vine or climbing vine	lookalike Virginia creeper Parthenocissus quinquefolia.
3 or 5 leaflets	—	—	woody stem (tree)	lookalike boxelder maple Acer negundo.
3 leaflets	asymmetric, with no petiolule	short petiolule	trailing vine	lookalike 🍓︎ strawberry genus Fragaria.
		medium-length petiolule	woody stem, with prickles if plant is above 🦵 knee-high	lookalike raspberry genus Rubus.
			shrub, North America (outside of California and southeastern 🇺🇸 USA)	sister-species X✋︎ western poison ivy Toxicodendron rydbergii ✋︎X
			trailing vine or climbing vine, with old growth held tight to host by 1000s of aerial roots, Asia or 🇨🇦 🇺🇸 🇲🇽 North America (outside the West, usually)	this plant, please continue below …

X🔥︎ DO NOT BURN 🔥︎X. Avoid all contact with smoke.

If contact with smoke, seek ⚕︎ medical attention with all due speed.

X⛽︎✂︎ DO NOT USE HEDGECLIPPERS ✂︎⛽︎X. Neither petrol/gasoline nor electric:

I met a guy whose petrol/gasoline hedgeclippers went through poison ivy before he noticed — plant fragments hit his 🫁 lungs, the poison entered his bloodstream, hitting all body organs horribly, and putting him under ⚕︎ medical care for months.
Perhaps a 😷 P100 HEPA respirator/filter mask would have helped, but I suggest sufficient PPE and ✂︎ hand tools, nice and slow!

X✋︎ DO NOT TOUCH ✋︎X. To avoid skin rash and irritation urushiol-induced contact dermatitis, avoid contact with all parts of this plant with your ✋︎ skin, 👕︎ clothing, 👟︎ shoes and 🐕︎ pets:

If contact with ✋︎ skin, quickly remove the oily-feeling urushiol with alcohol and a rag, or with 🧼💦︎ soap and water. I read that after 10 minutes, most of the agent has been absorbed into the skin — so if you notice contact, try to remove within this time.
If contact with 👕︎ clothing or 👟︎ shoes, wash them. For fabric, use normal laundry (some sources say in hot water; this author finds warm water adequate). For leather and suede, we have no idea (this author finds re-contact from 👟︎ boots and 🧤 gloves minor).
If contact with 🐕︎ pets, we have no idea.
If contact with ✂︎ tools, I try to avoid touching the blade until it has gone through soil or non-Toxicodendron wood a few times.

👥︎ People differ greatly in their reaction to this plant — some react strongly, some are immune, and most are in the middle:

On contact with the skin of susceptible individuals, a rash appears in a few hours to a day or two.
Without treatment, it clears up in 7 to 14 days.
With treatment, it clears up in a week or two.
This author finds minor contact ignorable. But If the urge to itch is strong, an antihistamine spray or pen (perhaps with 2% diphenhydramine) [disrecommended by this source] , perhaps followed by (after letting previous soak in) a commercial pink lotion, offers adequate relief for a few hours — use and repeat as directed by the labels.
One time, when this author had unseen contact with X✋︎ Pacific poison oak Toxicodendron diversilobum ✋︎X on the job, covering 100% of 💪︎ both arms, with patches on trunk caused by urushiol moved during a 💦︎ post-work shower, I did seek ⚕︎ medical attention.

Also called hiedra venenosa ("poison ivy" in 🇪🇸 Spanish). Also called Rhus radicans.

Despite its common name, not ☠︎ poisonous. Despite its scientific botanical name, not ☠︎ toxic, either. But a strong allergen to 👥︎ 70% of humans (85% after several exposures). [1]

Despite its common name, not an ☙ ivy genus Hedera, either. Instead, …

Part of sumac genus Toxicodendron in cashew/sumac family Anacardiaceae.

Native to Asia, and 🇨🇦 🇺🇸 🇲🇽 North America (except most of the West). 🗺 Map by county (🇺🇸 USA-48) (color key).

Uses by native peoples
(Ethnobotany database)

Toxicodendron hosts caterpillars of 5 species
of butterflies and moths, in some areas. Many 🐦︎ birds eat and love 🍒︎ poison ivy berries, and can be an important part of their diet. Other 🐢︎🐇︎🐜︎🐛︎ animals eat the plant itself.

Thus, this author removes poison ivy only from footpaths, and back one big step. More than one big step into the forest or bush, I leave alone, unless causing trouble somehow. Control Practices (page 3)

For 👥︎ humans, however, all parts of this plant are harmful, due to an oily-feeling group of chemicals called urushiol (see chart above).

At the end of the growing season, leaves turn bright red before most other deciduous plants.
