Age disparity in sexual relationships refers to sexual relations between people with a significant difference in age. Whether these relationships are accepted and the question of what counts as a significant difference in age has varied over time; and varies over cultures, different legal systems, and different ethical systems. It often depends on differing attitudes towards perceived social and economic differences between age groups and how consent is viewed, and sometimes whether or not the relationship is part of a spiritual or legal marriage.

Relationships with age disparity of all kinds have been observed with both men and women as the older or younger significant other. In the modern Western culture, older men often seek younger women. Older women sometimes date younger men as well, and in both cases wealth and physical attractiveness are often relevant.

On average in Europe, most men marry women around three years younger than themselves. A study released in 2003 by the United Kingdom's Office for National Statistics concluded that the proportion of women in England and Wales marrying younger men rose from 15% to 26% between 1963 and 1998. The study also showed a higher divorce rate as the age difference rose when the woman was older and a lower divorce rate as the age difference rose when the man was older.
