Sidi Khellil (Arabic: ﺳﻴﺪي ﺧﻠﻴﻞ) is a town and commune in El M'Ghair District, El M'Ghair Province, Algeria.

However, the area between the town (and the railway) and the N3 highway is occupied by an extensive palm plantation.

The endorheic salt lake Chott Felrhir lies about 10 kilometres (6 mi) to the northeast of the town.

The Biskra-Touggourt train line passes through the town, but there is no station.

The main road near the town is the N3 highway, which connect to Biskra to the north and Touggourt to the east.
