Actually, technically, I believe it is not a Berry or a Drupe, but a Pome making it a Pomaceous Fruit

Nicely illustrated site which explains the differences here:
A Pome is a fleshy fruit with a thin skin, not formed from the ovary but from another part of the plant. These are sometimes called Accessory Fruits. The seeds are contained in chambers in the centre of the fruit.
This is an Apple (Malus domestica). Other fruits of this type are: Firethorn (Pyracantha), Hawthorn (Crataegus), Medlar (Mespilus germanica), Pear (Pyrus communis), Quince (Cydonia oblonga).
