Mary Morgan, from Rostrevor, is said to be in serious but stable condition.
She was among 13 volunteers working in Kathiami with the Habitat for Humanity Northern Ireland Charity.
It was her fifth trip abroad with the organisation.
Five other volunteers were also injured in the crash.
The team were on their way to a building project when the accident happened on Tuesday.
Medical care was provided on the ground at the scene and all were then transferred to the general hospital in Nairobi for treatment.
The charity did not reveal the extent of the injuries of the most seriously hurt, but said the less seriously injured had broken bones.
A charity spokeswoman said the families of the injured had been informed and arrangements were being made for the immediate family of the most seriously injured to travel to Kenya.
A statement said: "Our immediate concern has been to ensure that all of those injured are receiving appropriate medical care and to liaise with and support their families.
"We have been in touch with the families of all of the team members and will be keeping them up to date as we get information from Kenya.
"We have set up a direct family communications phone number, 02890 262942."
The group had arrived in Kenya on Friday.
