Ion Armeanca (n. 1899, Săcărâmb, judeţul Hunedoara- d. 1954, Cluj-Napoca, judeţul Cluj), astronom, profesor universitar la Universitatea din Cluj, director al Observatorului din Cluj (1945-1954). S-a ocupat în special cu probleme de fotometrie şi este considerat un precursor al cercetării astrofizice din România.

Între anii 1928-1943 a efectuat mai multe cercetări astronomice şi a instalat un telescop de 0,5 m la Observatorul Astronomic din Cluj. Între 1934-1940, împreună cu Gheorghe Bratu, a efectuat mai multe observaţii şi calcule necesare întocmirii unei hărţi a cerului, intitulată Harta fotografică a cerului pentru secolul al XX-lea.

Principala sa ocupaţie ca astronom a fost fotometria, mai exact: variaţia strălucirii cometei Finsler 1937 f, magnitudinile vizuale ale stelelor variabile.
