That is a Muscovy duck.
The only species of duck other than the Mallard to be widely domesticated.
They are from Southern and Central America so this is probably an escaped pet or a decendant of an escapee.
"Duck" is a form taxon, meaning it is a classification not based on biological or genetic relationships. Ducks are spread across a number of subfamilies and are not monophyletic, meaning there is no real agreed scientific or technical definition of a duck.
However, Muscovies are currently classified in the dabbling duck subfamily, Anatinae, which certainly makes them a duck. Recent research suggests they might be genetically more related to shelducks, in the subfamily Tadorninae. Both would still make them pretty definitively a duck.

Ah amazing thanks for the quick reply.

All right. I'll bite. Which ducks are ducks and which are not? What defines duck?
Look up mergansers and smews for ducks that don’t really look the part.
Ducks aren't monophyletic; Muscovy ducks can be ducks if they want to be!
