Lusitanic is a word which refers to the shared linguistic and cultural traditions of the Lusophone (Portuguese-speaking) nations of Portugal, Brazil, Galicia, Macau, East Timor, Angola, Mozambique, Cape Verde, São Tomé and Príncipe and Guinea Bissau.

It is derived from the Roman name for the province which is now Portugal, Lusitania. It is an analogue of terms such as Anglo-Saxon and Hispanic, which describe the shared linguistic and cultural traditions of the English- and Spanish-speaking worlds, respectively; and is a way to avoid calling Brazil Hispanic, which under strict definitions of the word it is not. Like a Hispanic (or an Anglo-Saxon, in any case), a person with Lusitanic background may be of any race or ethnicity.

One of the cultural features unique to the Lusitanic world is a longing and melancholic feeling, that sometimes is expressed in such forms as fado music.
