National identity is a person's identity or sense of belonging to one or more states or one or more nations. It is the sense of "a nation as a cohesive whole, as represented by distinctive traditions, culture, and language". National identity may refer to the subjective feeling one shares with a group of people about a nation, regardless of one's legal citizenship status. National identity is viewed in psychological terms as "an awareness of difference", a "feeling and recognition of 'we' and 'they'". National identity also includes the general population and diaspora of multi-ethnic states and societies that have a shared sense of common identity identical to that of a nation while being made up of several component ethnic groups. Hyphenated ethnicities are examples of the confluence of multiple ethnic and national identities within a single person or entity.

Patriotism is the feeling of love, devotion, and a sense of attachment to a country or state. This attachment can be a combination of different feelings for things such as the language of one's homeland, and its ethnic, cultural, political, or historical aspects. It may encompass a set of concepts closely related to nationalism, mostly civic nationalism and sometimes cultural nationalism.
