At 53°33′41″N 2°19′36″W (53.5615°, −2.3268°) and 170 miles (274 km) northwest of central London, Radcliffe lies in the Irwell Valley on the course of the River Irwell.
The larger towns of Bury and Bolton lie to the northeast and northwest.
For the purposes of the Office for National Statistics, Radcliffe forms a northerly part of the Greater Manchester Urban Area, with Manchester city centre 6.5 miles (10.5 km) to the south-southeast.

Radcliffe's position on the River Irwell has proved important in its history and development as the river provided a source of water for local industry.
Radcliffe E'es, a level plain formed along the north bank of the Irwell during the previous ice age, is now derelict and the planned location of a new school.
From a highpoint of 500 feet (152 m) above sea level in the northwest of Radcliffe, the surface gradually descends, particularly in the south and east, being the lowest along the River Irwell.
The geology is represented by coal measure.


Radcliffe is surrounded by open space and rural land, much of which is visible from the town centre.
To the east of the town the River Roch flows under Blackford Bridge, and joins the Irwell shortly thereafter, along which several weirs and goits were built as it passes through the town.
Flowing from east to west the river divides the town on the north and south sides of the valley respectively.
The town centre sits on the north side of the valley.
Two road bridges cross the river: one in the former hamlet of Radcliffe Bridge, and another newer bridge built as part of the A665 Pilkington Bypass.
Another bridge crosses the river along the eastern border with Bury.
Various smaller pedestrian footbridges and two railway viaducts (one disused) also exist.
