Strong ground and psychic Pokemon such as Claydol, Metagross, and Tyranitar.
Both ground and psychic moves are super-effective against poison. They are both multiplied by 2. A good ground type move is earthquake, but since many poison Pokemon have levitate or are flying, they can avoid this.
It depends on dual types, abilities, available moves, etc., of both Pokemon, but the strongest Pokemon against poison Pokemon generally would be the strongest psychic and ground Pokemon. Some excellent psychic and ground Pokemon (strongest is quite subjective, so there's no definite answer) are Metagross and Tyranitar, respectively. Claydol is a strong Psychic and Ground dual-type Pokemon.

also a crobat or toxicroak, or lucario w/ poison jab
If it is a plain poison type it will be muk because there are 57 poison pokemon of which 18 Of them are plain poison without any sub type otherwise it is venosaur or nidoqueen
Psychic or ground type moves, be careful though, a few poison types have levitate so only psychic type moves will work.
