The Sheslay River is a tributary of the Inklin River in northwest part of the province of British Columbia, Canada.

{{BCGNIS|16283|Sheslay River}} It joins the Nahlin River to form the Inklin River, one of the main tributaries of the Taku River.{{cite book |last= Lord |first= Nancy |title= Rock, Water, Wild: An Alaskan Life |url= https://books.google.com/books?id=8XNzra78RK0C&pg=PA97 |accessdate= 12 August 2021 |date= 2009 |publisher= University of Nebraska Press |isbn= 0-8032-2609-8 |page= 97}} The lower Sheslay River marks the boundary between the Taku Plateau and the Nahlin Plateau. Its mouth at the Nahlin River marks the junction of the Taku, Nahlin, and Kawdy Plateaus. All three of these are part of the larger Stikine Plateau region.{{cite book |last= Holland |first= Stuart S. |title= Landforms of British Columbia: A Physiographic Outline |date= 1976 |publisher= Government of British Columbia |page= 137 |url= http://cmscontent.nrs.gov.bc.ca/geoscience/PublicationCatalogue/Bulletin/BCGS_B048.pdf |accessdate= 23 August 2021}}

The Sheslay River is in the traditional territory of the Taku River Tlingit First Nation, part of the Tlingit people.{{cite web |url= http://takhuatlen.org |title= T’akhu  Tlèn Conservancy |publisher= Taku Conservancy |accessdate= 12 August 2021}}

The Sheslay River originates in the Cheja Range of the Boundary Ranges, close to the headwaters of the Chutine River and the Stikine Icecap. It flows generally north about {{convert|150|km|mi|abbr=on}}Length measured using Google Maps path tool, BCGNIS coordinates, topographic maps, and [http://www.topoquest.com/ TopoQuest]. to join the Nahlin River.{{bcgnis|19279|Nahlin River}} The confluence of the Sheslay and Nahlin Rivers marks the beginning of the Inklin River.{{bcgnis|2913|Inklin River}} The mouth of the Sheslay River is located about {{convert|145|km|abbr=on}} northeast of Juneau, Alaska and about {{convert|110|km|abbr=on}} northwest of Telegraph Creek, British Columbia.

The Sheslay River's watershed covers {{convert| 3342 |km2|abbr=on}}, and its mean annual discharge is {{convert|65.3|m3/s|cuft/s|abbr=on}}.{{cite web |url= https://nwwt.bcwatertool.ca |title= Northwest Water Tool |work= BC Water Tool |publisher= GeoBC, Integrated Land Management Bureau, Ministry of Agriculture and Lands, Government of British Columbia |accessdate= 12 August 2021}}

Major tributaries of the Sheslay River include Shearer Creek,{{BCGNIS|39605|Shearer Creek}} Moosehorn Creek,{{BCGNIS|39564|Moosehorn Creek}} Hackett River and Egnell Creek,{{bcgnis|5171|Hackett River}}{{BCGNIS|2275|Egnell Creek}} Samotua River,{{bcgnis|19327|Samotua River}} and Tatsatua Creek.{{bcgnis|19392|Tatsatua Creek}} The middle Sheslay River, above the Samotua River, lies between the Chechidla Range and Level Mountain. The small settlement of Sheslay is located at the confluence of the Sheslay and Hackett Rivers. The lower Sheslay River, below the mouth of the Samotua River, flows just south and west of Heart Peaks, part of the Nahlin Plateau. The lowermost Sheslay River flows between the Taku and Nahlin Plateaus. Its confluence with the Nahlin River forms the Inklin River.

The Sheslay River supports a number salmonids, including Chinook salmon, coho salmon, sockeye salmon, steelhead trout, rainbow trout, lake trout, Dolly Varden trout, bull trout, and round whitefish. It also supports populations of coastrange sculpin and slimy sculpin.{{cite web |url= http://www.legis.state.ak.us/basis/get_documents.asp?session=27&docid=6357 |title= Taku River Fish Populations |publisher= Alaska State Legislature |accessdate= 12 August 2021}}
