The hypothalamus is part of an organ - that being the brain. It isn't a gland, because it only secretes hormones locally. The pituitary is a gland because it secretes hormones into the bloodstream for distant effects.
hypothalamus - a region in the upper part of the brainstem that acts as a relay to the pituitary gland - it controls body temperature, circadian cycles, sleep, moods, hormonal body processes, hunger, and thirst. The hypothalamus is part of the limbic system and works with the pituitary gland.
It would be an overstatement that a gland is responsible for sleep, however, the pineal gland does have some connection to sleep. It secretes a hormone called melatonin which contributes to sleepiness.
Melatonin. Regulates sleep
The hypothalamus is located below the thalamus and is connected to it through various neural pathways. They are both part of the diencephalon in the brain and play important roles in regulating various body functions, including the endocrine system and the sleep-wake cycle.
Reticular formation.
The brainstem and hypothalamus regulate sleep-wake cycles. The pineal gland produces melatonin, a hormone that helps control sleep patterns. The thalamus also plays a role in promoting sleep by shutting off sensory information to the cerebral cortex.
