The town is situated near the confluence of both headwater rivers (Jiul de Vest and Jiul de Est) of the Jiu, north of the Vâlcan Mountains and in the eastern foothills of the Retezat Mountains. Most of the town was built along Aninoasa creek, and the town is actually separated into two areas by the Jiul de Vest. "Anin" means "alder tree" in Romanian.
Aninoasa is located at the southern extremity of Hunedoara County, about 98 km (61 mi) from the county seat, Deva, on the border with Gorj County. The village of Iscroni is crossed by national roadDN66A [ro], which leads west to Vulcan, 5 km (3.1 mi) away, and Lupeni, 11 km (6.8 mi) away, and east to European route E79 and the city of Petroșani, 7 km (4.3 mi) to the northeast.
The Iscroni train station serves the CFRLine 214, a 17 km (11 mi) railway from Livezeni (in Petroșani) to Lupeni.
