11-Deoxycorticosterone (DOC), or simply deoxycorticosterone, also known as 21-hydroxyprogesterone, as well as desoxycortone (INN), deoxycortone (BAN), and cortexone, is a steroid hormone produced by the adrenal gland that possesses mineralocorticoid activity and acts as a precursor to aldosterone. It is an active (Na+-retaining) mineralocorticoid. As its names indicate, 11-deoxycorticosterone can be understood as the 21-hydroxy- variant of progesterone or as the 11-deoxy- variant of corticosterone.

DOC is a potent mineralocorticoid but is virtually devoid of glucocorticoid activity. However, 11β-hydroxylation of DOC produces corticosterone and confers glucocorticoid activity, along with 10-fold reduced mineralocorticoid activity. In addition to its mineralocorticoid activity, DOC has been found to possess one-third to one-tenth the potency of progesterone as a progestogen when administered systematically to rabbits. However, it has no such activity when applied directly to the uterine mucosa of mice. The discrepancy may be related to the fact that DOC can be converted into progesterone in vivo.

DOC is a precursor molecule for the production of aldosterone. The major pathway for aldosterone production is in the adrenal glomerulosa zone of the adrenal gland. It is not a major secretory hormone. It is produced from progesterone by 21β-hydroxylase and is converted to corticosterone by 11β-hydroxylase. Corticosterone is then converted to aldosterone by aldosterone synthase.
