π Bonds are delocalized because their elections are not confined to a single atom.

Explanation:

For example, consider the π bond in ethylene.

Before the #"p"# orbitals overlap, the #"p"# electrons are confined to (or "localized" on) each carbon atom.

However, the electrons in the π bond are free to roam over both carbon atoms.

That is, the electrons in the π bond are "delocalized".
