The plural for octopus is both octopi and octopuses.
Octopuses or octopodes. The Anglicized (and most common) plural form of octopus is octopuses. Although it is often supposed that octopi is the 'correct' plural of octopus, and it has been in use for longer than the usual Anglicized plural octopuses, it in fact originates as an error. Octopus is not a simple Latin word of the second declension, but a Latinized form of the Greek word oktopous, and its 'correct' plural would logically be octopodes.
People often have the common misconception of thinking that it's octupi. Just that most English words that end in -us come from a Latin 2nd declension noun: and the (nominative) plural of those end in -i. In fact, however, it derives from Ancient Greek and is in fact octopodes. Although octupuses is also widely accepted.
Grammatically speaking, the correct classical plural of the word octopus should be octopodes, though the word octopuses is also used in English.
The word octopi would indicate a Latin plural noun in the second declension, which the word octopus does not lend itself to.
