#### **Abstract**

Grapevine (*Vitis vinifera*) is one of the most important commercial plants since its berries are used for wine production or consumed as fresh fruit or dry fruit. Many studies have focused on berry development and have pointed out the hormonal regulation on the three phases, from early development to maturity. Grapevine fruit has been classified as non-climacteric based on the low levels of ethylene present around *véraison*, although recent evidence has suggested a role for this hormone during grape berry ripening. The control of different physiological processes depends on a complex integration between environmental cues and endogenous factors, which is mediated by a phytohormone crosstalk. In this chapter, we will focus on phytohormones, their signaling pathways, and their association to berry development in *V*. *vinifera*; in particular, we will refer to auxins, abscisic acid, brassinosteroids, ethylene, gibberellins, and cytokinins.
