The Ljalja ( Russian Ляля ) is a 242 km (with the longer headstream 258 km) long right tributary of the Sosva on the eastern side of the Ural Mountains and west of the West Siberian lowlands in Russia .

The Lyalja empties about 80 km as the crow flies west of the city of Novaya Lyalya, named after it, and 270 km north-north-west of Yekaterinburg from the 16 km long source river Poludennaja Lyalja ("Midday Lyalja") from the right (south) and the 15 km long Kolodnitschnaja Lyalja ( of russian kolodki, as " foot block -Ljalja") from the left. These in turn arise at a height of 500–550 m below the 851  m high mountain Ljalinski Kamen. The Ljalja flows through the taiga area east of the Ural main ridge in a predominantly easterly direction, initially in wide arches in a relatively narrow valley through an eastern foothill, later increasingly meandering through flatter, swampy area. It finally flows into the Soswa above the village of Romanowo and a good 50 km east of Novaya Lyalia. The river name comes from the Mansi language and means warm.

The catchment area of the river covers 7430 km². The most important tributaries are the Lobwa (length 222 km) from the left and the Bolshaya Nyasma ("Great Nyasma", 92 km) from the right.

The discharge at the village of Srednesaltanowo, 88 km above the mouth and above the confluence of the largest tributary Lobwa, is an annual mean of 16.06 m³ / s, with a maximum monthly mean of 59.44 m³ / s in May and a minimum monthly mean of 2.16 m³ / s in March.

The Lyalja flows along its entire length through the territory of the Sverdlovsk Oblast , the source river Poludennaja Lyalja for a few kilometers that of the Perm region . The largest place on the river is the town of Novaya Lyalya ("New Lyalja") on the middle reaches. There it crosses the Kuschwa  - Serow railway line and the R352 Yekaterinburg - Serow regional road that follows it. Further upstream are the larger settlements and former gold mining centers Staraya Ljalja ("Old Lyalja ") and Pavda ( urban-type settlement until 2004 ).
