The Superior salivary nucleus (or superior salivatory nucleus) of the facial nerve is a visceromotor cranial nerve nucleus located in the pontine tegmentum.

Parasympathetic efferent fibers of the facial nerve (preganglionic fibers) arise according to some authors from the small cells of the facial nucleus, or according to others from a special nucleus of cells scattered in the reticular formation, dorso-medial to the facial nucleus. This is sometimes called the superior salivatory nucleus.

These preganglionic fibers are distributed partly via the chorda tympani and lingual nerves to the submandibular ganglion, thence by postganglionic (vasodilator) fibers to the submandibular gland and sublingual gland.

Some of the preganglionic fibers pass to the sphenopalatine ganglion via the greater petrosal nerve.

The term "lacrimal nucleus" is sometimes used to refer to a portion of the superior salivary nucleus. [BrainInfo|ancil|329]
