David Lincoln Rabinowitz (born 1960) is a researcher at Yale University. He has built CCD cameras and software for the detection of near-Earth asteroids and Kuiper Belt Objects, and his research has helped reduce the assumed number of near-Earth asteroids larger than 1 km by half, from 1,000–2,000 to 500–1,000 He has also assisted in the detection of distant solar system objects, supernovae, and quasars, thereby helping to understand the origin and evolution of the solar system and the dark energy driving the accelerated expansion of the universe.
Collaborating with Michael E. Brown and Chad Trujillo of the Quasar Equatorial Survey Team, he has participated in the discovery of several plutoids:
- 90377 Sedna, possibly the first known inner Oort cloud object.
- 90482 Orcus
- Eris, more massive than Pluto.
- Haumea
- Makemake
although he would not get credit for Haumea.
Together with Tom Gehrels of the University of Arizona and his Spacewatch Team, Rabinowitz discovered or co-discovered other astronomical objects including:
- 5145 Pholus
- 1991 BA

“I hope we may say that thus, this fateful morning, came to an end all wars.”
—David Lloyd George (1863–1945)
“He has the earnestness of a prophet. In an age of pedantry and dilettantism, he has no grain of these in his composition. There is nowhere else, surely, in recent readable English, or other books, such direct and effectual teaching, reproving, encouraging, stimulating, earnestly, vehemently, almost like Mahomet, like Luther.... His writings are a gospel to the young of this generation; they will hear his manly, brotherly speech with responsive joy, and press forward to older or newer gospels.”
—Henry David Thoreau (1817–1862)
