Hypomania (literally "under mania" or "less than mania") is a mood state characterized by persistent disinhibition and pervasive elevated (euphoric) with or without irritable mood but generally less severe than full mania. According to DSM-V criteria, hypomania is specifically distinct from mania in that there is no psychosis (sensing things others do not sense in the same environment); mania, by DSM-V definition, has psychotic features. Characteristic behaviors are extremely energetic, talkative, and confident commonly exhibited with a flight of creative ideas. While hypomanic behavior often generates productivity and excitement, it can become troublesome if the subject engages in risky or otherwise inadvisable behaviors. When manic episodes are "staged" according to symptomatic severity and associated features, hypomania constitutes the first stage, or stage I, of the syndrome, wherein the cardinal features (euphoria or heightened irritability, pressure of speech and activity, increased energy and decreased need for sleep, and flight of ideas) are most plainly evident.

The Ancient Greek physician Hippocrates called one personality type 'hypomanic' (Greek: ὑπομαινόμενοι, hypomainómenoi). In 19th century psychiatry, when mania had a broad meaning of craziness, hypomania was equated by some to concepts of 'partial insanity' or monomania. A more specific usage was advanced by the German neuro-psychiatrist Emanuel Ernst Mendel in 1881, who wrote, "I recommend, taking into consideration the word used by Hippocrates, to name those types of mania that show a less severe picture, 'hypomania'". Narrower operational definitions of hypomania were developed from the 1960s/1970s.

Individuals in a hypomanic state have a decreased need for sleep, are extremely outgoing and competitive, have a great deal of energy and are otherwise often fully functioning (unlike full mania).

Specifically, hypomania is distinguished from mania by the absence of psychotic symptoms and grandiosity, and by its lesser degree of impact on functioning.
