La formaldeide (o aldeide fòrmica, nome IUPAC: metanale) è la più semplice delle aldeidi. La sua formula chimica è CH2O, o anche H2C=O. A temperatura ambiente è un gas incolore, infiammabile, dal caratteristico odore pungente e fortemente irritante, solubilissimo in acqua (~400 g/L). Il suo monomero idrato, erroneamente considerato una sua soluzione acquosa al 37%, è commercialmente noto anche con il nome di formalina o formolo.
