thumb|261x261px|Non-ionic Cycloadditions In organic chemistry, a cycloaddition is a chemical reaction in which "two or more unsaturated molecules (or parts of the same molecule) combine with the formation of a cyclic adduct in which there is a net reduction of the bond multiplicity". The resulting reaction is a cyclization reaction. Many but not all cycloadditions are concerted and thus pericyclic. Nonconcerted cycloadditions are not pericyclic. As a class of addition reaction, cycloadditions permit carbon–carbon bond formation without the use of a nucleophile or electrophile.

Una cicloadición es una reacción pericíclica en la que dos enlaces π se pierden y se forman dos enlaces σ. La reacción resultante es una reacción de ciclación. Las cicloadiciones suelen ser descritas por el tamaño del esqueleto de los participantes. Esto hace que la reacción de Diels-Alder sea una cicloadición [4+2], la cicloadición 1,3-dipolar una cicloadición [3+2], etc.
