Henry Gellibrand (1597–1637) was an English mathematician. He is known for his work on the Earth's magnetic field. He discovered that magnetic declination – the angle of dip of a compass needle – is not constant but changes over time. He announced this in 1635, relying on previous observations by others, which had not yet been correctly interpreted. He was the son of the physician Henry Gellibrand (1568–1615) and Mary Faversham. His four younger brothers were John, Edward, Thomas and Samuel. Sam
