Mr Quinney will take on his role as of October 1, 2016, along side NFU Mutual’s 12 strong board.
The board includes eight non-executive directors, half with farming expertise and the other half with wider commercial expertise.
Adam, who has served as NFU Mutual’s regional advisory board chairman for the Midlands since 2014, was NFU Vice President from 2012 to 2014.
His NFU work included serving on the National Livestock Committee and Animal Health Working Group and has chaired the England Farm Safety Partnership.
Outside the NFU, Adam has also served on the EBLEX Board; he became the first English ASDA beef scholar, and is a trustee of the Studley College Trust.
He farms 150 hectares (370 acres) at Sambourne, near Redditch, on the Worcestershire-Warwickshire border. The enterprise includes a suckler cattle and beef finishing, breeding ewes and 40 hectares of arable crops.
Mr Quinney said: “NFU Mutual is part of the bed-rock of UK agriculture. Since 1910 it has been protecting farming families and remains a mutual run for the benefit of our members.
“I will be working to ensure that NFU Mutual continues to provide the right products and renowned local service to its members and supports them through the current challenging times for farmers.”
