This is a list of multiple births, consisting of notable higher order (4+) multiple births and pregnancies. Twins and triplets are sufficiently common to have their own separate articles. With the use of reproductive technology such as fertility drugs and in vitro fertilization (IVF) such births have become increasingly common. This list contains only multiple births which have some claim to notability, such as being the first recorded in a country, the first to survive to adulthood in a country, or the heaviest, lightest or longest lived (globally).
