Joseph A. Hardy III (born 1923) is the founder and CEO of the 84 Lumber Company.

Joe Hardy was raised by middle class parents in the jewelry business, but the experiences of the Great Depression taught him the value of hard work. To support himself in college, he sold fresh fruit door to door. After Hardy graduated from the University of Pittsburgh with a degree in industrial engineering, he took the advice of a close friend and opened the Green Hills Lumber Company. After a few years, in 1956, Hardy joined his younger brothers, and together they opened a “cash and carry” lumber yard in the rural town of Eighty Four, Pennsylvania. Hardy liked the name of the small town and decided to name his new company 84 Lumber. Because of his successful management of the company, 84 Lumber is now the 3rd largest home improvement chain in the United States.

Hardy also developed the Hardy family-owned Nemacolin Woodlands Resort. The resort features three hotels, including the new Falling Rock hotel and clubhouse, Woodland Spa, a Hummer off-road course, a shooting academy, and multiple onsite restaurants. The resort is also home to the Mystic Rock golf course, designed by Pete Dye, and home to the PGA Tour's Eighty-Four Lumber Classic from 2002-2006. Hardy celebrated the 2004 Eighty-Four Lumber Classic extravagantly, providing the crowds with a concert featuring Rocket Star and Smash Mouth.

In addition to his involvement in 84 Lumber and Nemacolin Woodlands Resort, Hardy began a 4 year term in 2004 as Vice Chairman of the Board of Commissioners of Fayette County where he lives. Hardy is leading a multi-million dollar renovation of Uniontown, the largest city in the county, donating millions of dollars to support street and building improvements and construction of green spaces. Hardy has received various awards from the local community for his charitable donations.

Hardy announced on Sunday, September 9, 2007 at a tailgate party at Nemacolin Woodlands Resort that he is backing out of the 2007 general election for Fayette County commissioner. Hardy finished first in vote getting in the 2007 primary for Fayette County commissioner.http://www.heraldstandard.com/site/news.cfm?newsid=18800032&BRD=2280&PAG=461&dept_id=480247&rfi=6
