Naţionalitate român
Născut 30 martie 1901, Iertof, judeţul Caraş-Severin
Decedat 2 martie 1977, Timişoara
Ocupaţie astronom, seismolog

Ioan Curea (n. 30 martie 1901, Iertof, judeţul Caraş-Severin - d. 2 martie 1977, Timişoara) a fost un astronom şi seismolog român. A construit un seismograf orizontal, având un pendul de 540 kg şi un amortizor de aer, înregistrarea datelor fiind mecanică. A stabilit o metodă nouă pentru a determina erorile periodice ale şuruburilor micrometrice. În urma cercetărilor sale a stabilit un procedeu de aproximare liniară pentru determinarea oscilaţiilor solului în cutremure şi a imaginat formule matematice noi pentru corecţii diferenţiale de refracţie, de aberaţie sau paralaxă anuală. A dotat observatorul astronomic şi staţia seismografică din Timişoara cu aparatură de producţie proprie şi a construit planetariul din Timişoara.

A înfiinţat mai multe publicaţii de specialitate: Bulletin seismique de la station seismique de l'Universite de Cluj (1940), Bulletin seismique de la station de Timisoara (1943-1950), Observaţii seismometrice la staţia seismografică a Institutului politehnic din Timişoara (1950-1977).
