In grammar, a future tense (abbreviated FUT) is a verb form that generally marks the event described by the verb as not having happened yet, but expected to happen in the future. An example of a future tense form is the French aimera, meaning "will love", derived from the verb aimer ("love"). The "future" expressed by the future tense usually means the future relative to the moment of speaking, although in contexts where relative tense is used it may mean the future relative to some other point in time under consideration.

English does not have an inflectional future tense, though it has a variety of grammatical and lexical means for expressing future-related meanings. These include modal auxiliaries such as will and shall as well as the futurate present tense.
