Idea

A cocartesian monoidal category is a monoidal category (𝒞,0,)\big(\mathcal{C}, 0, \sqcup \big) whose monoidal product functor :𝒞×𝒞𝒞\sqcup \,\colon\, \mathcal{C} \times \mathcal{C} \to \mathcal{C} is given by the coproduct (and so whose tensor unit is an initial object00”).

This is the dual notion of that of a cartesian monoidal category.

Sometime we refer to a category as cocartesian monoidal just to indicate that it has all finite coproducts.
