Bruce McPherson Beehler (born October 11, 1951, in Baltimore) is an ornithologist and research associate of the Bird Division of the Smithsonian Institution's National Museum of Natural History.

Bruce Beehler graduated from Williams College and received his master's degree and PhD studying the behavioral ecology of the birds-of-paradise at Princeton University.

To the general public, Beehler is best known for having co-led a widely published rapid assessment survey on biological diversity in 2005 to the Foja Mountains, Papua, where he, together with an international team of 11 scientists, the majority from the Indonesian Institute of Sciences (LIPI), made a number of scientific discoveries.

The findings on this survey expanded on previous research conducted in the region by Dr. Jared Diamond in the late 1970s and early 1980s.

Together with a team from 60 Minutes, Beehler returned to the Foja Mountains in 2007, resulting in the first ever filming of several of the species discovered in 2005, as well as encounters with an undescribed giant rat (Mallomys sp.)
