Albert Warren "Tillie" Tillinghast (May 7, 1876 – May 19, 1942)[2][3] was an American golf course architect.

He lived with his wife Lillian in Beverly Hills, California, and died at his daughter Marion Frances's home in Toledo, Ohio, in 1942.

[6] Tillinghast-designed courses have hosted multiple professional golf major championships—the 1927, 1928, 1938 and 1949 PGA Championships, contested at Cedar Crest Park, Baltimore Country Club, Shawnee and Hermitage Country Club, respectively; the 2005 and 2016 PGA Championship, contested at Baltusrol Golf Club, which has also been the host of seven U.S.

He also designed Oak Hills Country Club in San Antonio, which hosted the Texas Open 24 times between 1960 and 1994.

Tillinghast was also the uncredited co-designer of several green complexes at Century Country Club in Purchase.
