Kriens is a municipality in the district of Lucerne in the canton of Lucerne in Switzerland.
The municipality lies at the foot of Mount Pilatus, and is a western suburb of Lucerne.
The border in the east, with the neighboring community of Lucerne, goes across the property of a large brewery. From there it runs in a north-westerly direction through the Gigeliwald and runs to the west of the Lucerne district of Obergütsch and the Gütschwald to the Böschenhof farmstead. From there it runs to the south-west up the slopes of Mount Sonnenberg and Mount Blettenberg to the Gspan farmstead. It turns thence to the south-east, separating the hamlet of Holderchäppeli (elev. 935 m), running over Mount Würzenegg (elev. 1146 m), Mount Chraigütsch (elev. 1081 m) and Mount Höchberg (elev. 1162 m) on its way to Mount Lauelenegg (elev. 1442 m) northwest of Mount Pilatus. Thence the municipal border leads to the north-east over Mount Fräkmüntegg (elev. 1469 m), and Mount Biele (elev. 1373 m) to the Hochwald. From there the border leads to Steinibach and shortly thereafter, nearly to the train station in Horw. From there it follows the train track toward Lucerne in a north-easterly direction back to the property of the brewery.
The eastern part of Kriens (the districts near the city and near Horw) lie in a valley. From Kupferhammer the land gently rises to the west, toward Obernau (elevation difference between Kupferhammer and Obernau less than 90 m).
To the north of the town is the little-forested southern slope of Mount Sonnenberg. The slope to the south of town is the northern side of Mount Schattenberg.
Mount Schattenberg is the first rise of Mount Pilatus. The lower part is cleared and partially developed. The majority of the land west of Obernau and south of town is forest. West of the line connecting Krienseregg and Fräkmüntegg there is a large, flat swamp, from which begin many brooks (including Tschuggenbach, Weissbach, Rotbach, and Renggbach). The whole area forms part of the north slope of Mount Pilatus.
Of importance is the stream the Unterer Krienbach, which often caused floods before it was covered. It flows through the town and empties into the Reuss River in Lucerne. The Schlundbach and the previously mentioned Steinibach flow in the direction of Horw and onward into Lake Lucerne.
The municipal land area of 27.34 square kilometres is just over slightly half covered in forest (50.5%). About a sixth (16.9%) is developed, and the remaining 31.6% is used for agriculture.

Despite this, Kriens has an outstanding public transportation system. Line 1 of the VBL bus company goes from Lucerne to Kriens-Obernau via the town center. Lines 15 and 16 make other communities accessible by public transportation. In 2005, Line 16 was extended to the train station in Horw. Additionally, the new Line 31 goes from Lucerne to Horw via many communities in Kriens.
Kriens has its own exit on the Autobahn (the A2) near Grosshof, south of the Mount Sonnenberg tunnel. However, the exit for Horw, in Schlund, also on the A2, is more convenient for inhabitants in some parts of Kriens.
The town was started by a monk named Jacobous Kriens years ago. Many people used the name of the town as their last name when they left years ago.
