Forest Ray Moulton was an American astronomer. He was born in Le Roy, Michigan, and was educated at Albion College. After graduating in 1894, he performed his graduate studies at the University of Chicago and gained a Ph.D. in 1899. At the University of Chicago he was associate in astronomy (1898–1900), instructor (1900–03), assistant professor (1903–08), associate professor (1908–12), and professor after 1912.

- Forest Ray Moulton was an American astronomer. He was born in Le Roy, Michigan, and was educated at Albion College. After graduating in 1894, he performed his graduate studies at the University of Chicago and gained a Ph.D. in 1899. At the University of Chicago he was associate in astronomy (1898–1900), instructor (1900–03), assistant professor (1903–08), associate professor (1908–12), and professor after 1912. He is noted for being a proponent, along with Thomas Chamberlin, of the Chamberlin-Moulton planetesimal hypothesis that the planets coalesced from smaller bodies they termed planetesimals. Their hypothesis called for the close passage of another star to trigger this condensation, a concept that has since fallen out of favor. In the first decades of the twentieth century, some additional small satellites were discovered to be in orbit around Jupiter. Dr. Moulton proposed that these were actually gravitationally-captured planetesimals. This theory has become well-accepted among astronomers. The crater Moulton on the Moon, the Adams-Moulton methods for solving differential equations and the Moulton plane in geometry are named after him.
- Forest Ray Moulton war ein US-amerikanischer Astronom, Mathematiker und Wissenschaftsorganisator.
- Astronomo a Chicago. Intorno al 1900, insieme al geologo statunitense T. C. Chamberlin, formula una congettura sulla formazione del sistema solare attribuita al passaggio di una stella nelle vicinanze del sole che per effetto di marea avrebbe provocato il distacco di materiale solare; questo materiale gassoso per successivo raffreddamento avrebbe fatto nascere i cosiddetti planetesimali successivamente aggregatisi in asteroidi e pianeti. Nel 1902 propone un piano non desarguesiano piuttosto semplice ora noto come piano di Moulton. Nell'ambito della AAAS copre la carica di Permanent Secretary dal 1937 al 1946 e quella di Administrative Secretary dal 1946 al 1948.
- フォレスト・モールトン（Forest Ray Moulton、 1872年4月29日 - 1952年12月7日）はアメリカ合衆国の天文学者である。 ミシガン州のルロイに生まれた。アルビオン・カレッジを卒業した後、1899年にシカゴ大学で博士号をえた。シカゴ大学教授、アメリカ科学振興協会 の事務長を務めた。 トーマス・チェンバレンと、太陽の近くを別の天体が通過し、その潮汐力で太陽から噴出した物質が冷却されて惑星群を形成したというモールトン・チェンバレン説の提案者であるが、現在この説は信じられていない。20世紀の始め、木星の新しい衛星が発見されると、これらの衛星が木星の重力にとらえられた小惑星であるという理論を示した。 小惑星(993) モールトナはモールトンの名前に因んで命名された。月のクレータに命名されている。
