This is what we Romanians call “pancakes” (clătite). In the US for example, these are not “pancakes”. What Americans call “pancakes”, we call “clătite americane” (American pancakes) or just “pancakes” (the untranslated English word).
Note: some French regions also call them "galettes", either depending on the type of flour used, or on the type of toppings (sweet for crêpes, salty for galettes).
It is too! Galette des rois is what we traditionally eat during epiphany. It is most often a puff pastry with almond-flavoured custard (frangipane), but there are other kinds too. More generally, galette is a generic word for a round and flat object.
