The former Ulster and Ireland star led the province to Heineken Cup glory in 1999.
After retiring he became a key part of the Ulster management team, taking up the role of Operation Director, before becoming Director of Rugby four years ago.
He helped persuade a number of top stars, including Ruan Pienaar, to come to Ravenhill.
Humphreys will join departing Ulster and All Blacks prop John Afoa at Kingsholm.
"This was a really difficult decision for me personally but having received a direct approach from Gloucester, I have now chosen to accept an offer to become their Director of Rugby. It is, I believe, the right move for me at this stage of my career," Humphreys said.
"I would like to thank the supporters and all those involved in Ulster Rugby over more than two decades who have lent me support, encouragement and wisdom."
We are disappointed with the decision but respect David's decision to leave Ulster.

Humphreys added: "There is no doubt that the province will continue to move forward. It has a fantastic stadium, the best supporters and a wealth of great talent coming through. Ulster Rugby will be a force within rugby for many years to come."
Chief Executive of Ulster Rugby, Shane Logan, said: "I would like to wish David every success with Gloucester and to thank him for the outstanding contribution that he has made to Ulster Rugby.
"As Director of Rugby, David has helped to grow the game at all levels - there are more people playing rugby in the Province than ever before, we have successful age-grade sides, we have a strong Academy and we now have a senior squad that can beat the best in Europe.
"We do know we already have the structures in place to ensure we have success in the long term.
"Ulster Rugby will now begin the process of recruiting a new Director of Rugby and we look forward to building on the progress that the Province has made in recent years."
