These two are identified with one another in the record, which is not the same as being the same figure. The same inherited Indo-European sky-father, and the textbook case of interpretatio romana.

Common questions
Are Jupiter and Zeus the same figure?
These two are identified with one another in the record, which is not the same as being the same figure. The same inherited Indo-European sky-father, and the textbook case of interpretatio romana. ColossiansOne records the link rather than asserting the identity: where texts disagree about whether two names denote one figure, the disagreement is what gets shown.
Which is older, Jupiter or Zeus?
Zeus is the older name: first attested around c. 700 BCE, against c. 500 BCE for Jupiter. Where the two dates are far apart, that gap is the whole reason the pair is worth comparing.
Do any texts name both Jupiter and Zeus?
Yes — 1 text names both. A single text naming both figures is the strongest evidence available here that its author treated them as distinct, whatever later writers did with the pair.
