Daniel B. Luten also known as Daniel Benjamin Luten (Dec. 26, 1869-July 3, 1946) was an American bridge builder and engineer based in Indianapolis, Indiana.

He designed and patented the Luten arch, a type of concrete arch bridge. He obtained more than 30 patents eventually, including various refinements of design that used transverse and other reinforcement which allowed bridges to be lighter. "By 1919, Luten claimed to have designed some 17,000 arches, and stated that examples of his designs could be found in all but three states of the Union. Indiana alone had some 2,000 Luten arches." He was born in Grand Rapids, Michigan in 1869.

He graduated from the University of Michigan in 1894, in civil engineering. He was an instructor, in architectural and sanitary engineering, for Purdue University from 1895 to 1900. He resigned in 1900 to conduct the bridge company work.

A number of bridges that are listed on the U.S. National Register of Historic Places are credited to him, including (with specific attribution):

Additional Luten arch bridges are NRHP-listed that are attributed to the Luten Bridge Company or to Topeka Bridge & Iron Co., two firms which had use of Luten's patented designs.
