In mathematics, rearrangement refers to altering the order of elements in a sequence or series. The rearrangement inequality relates sums of products of paired sequences after rearranging their terms. The Riemann rearrangement theorem shows that a conditionally convergent series can be rearranged to converge to any given sum or to diverge.

In chemistry, rearrangement describes a class of reactions in which atoms in a molecule shift to form a different structural arrangement, often via carbocation intermediates. Notable examples include the Wagner–Meerwein rearrangement and the pinacol rearrangement. The products are called rearranged products.

In biology and genetics, chromosomal rearrangements refer to structural changes in chromosomes, such as inversions, translocations, or duplications that produce rearranged genomes.
