Gay pride, LGBT pride or simply pride is the positive stance against discrimination and violence toward lesbian, gay, bisexual, and transgender (LGBT) people to promote their self-affirmation, increase their visibility as a social group, build community, and celebrate sexual diversity and gender variance. Pride, as opposed to shame and social stigma, is the predominant outlook that bolsters most LGBT rights movements throughout the world. What’s more, pride has lent its name to LGBT-themed organizations, institutes, foundations, book titles, periodicals and even a cable TV station and the Pride Library.

Ranging from solemn to carnivalesque, pride events are typically held during LGBT Pride Month or some other time that commemorates a turning point in a country’s LGBT history, for example Moscow Pride in May for the anniversary of Russia's 1993 decriminalization of homosexuality. Some types of pride events include LGBT pride parades and marches, rallies, commemorations, community days, dance parties, and large festivals such as Sydney Mardi Gras, which spans several weeks.

Gay is a word (a noun or an adjective) that primarily refers to a homosexual person.

The term was originally used to refer to feelings of being "carefree", "happy", or "bright and showy"; it had also come to acquire some connotations of "immorality" as early as 1637. The term's use as a reference to homosexuality may date as early as the late 19th century, but its use gradually increased in the 20th century. In modern English, gay has come to be used as an adjective, and as a noun, referring to the people, especially to men, and the practices and cultures associated with homosexuality. By the end of the 20th century, the word gay was recommended by major LGBT groups and style guides to describe people attracted to members of the same sex. At about the same time, a new, pejorative use became prevalent in some parts of the world. In the Anglosphere, this connotation, among younger speakers, has a derisive meaning equivalent to rubbish or stupid (as in "That's so gay."). In this use, the word does not mean "homosexual", so it can be used, for example, to refer to an inanimate object or abstract concept of which one disapproves. This usage can also refer to weakness or unmanliness. When used in this way, the extent to which it still retains connotations of homosexuality has been debated and harshly criticized.

Pride is an inwardly directed emotion that carries two common meanings. With a negative connotation, pride refers to an inflated sense of one's personal status or accomplishments, often used synonymously with hubris. With a positive connotation, pride refers to a satisfied sense of attachment toward one's own or another's choices and actions, or toward a whole group of people, and is a product of praise, independent self-reflection, or a fulfilled feeling of belonging. Philosophers and social psychologists have noted that pride is a complex secondary emotion which requires the development of a sense of self and the mastery of relevant conceptual distinctions (e.g., that pride is distinct from happiness and joy) through language-based interaction with others. Some social psychologists identify it as linked to a signal of high social status. In contrast pride could also be defined as a disagreement with the truth. One definition of pride in the first sense comes from St. Augustine: "the love of one's own excellence". In this sense, the opposite of pride is either humility or guilt; the latter in particular being a sense of one's own failure in contrast to Augustine's notion of excellence.
