41號美國國道商業線(英語:Business US Highway 41)是一條曾隸屬於41號美國國道的商業線,其起點和終點皆為與28號州道共線的41號國道。該商業線曾作為密歇根州高速幹線系統(Michigan State Trunkline System)的一部分,並全程與當地兩條於19世紀中期馬凱特市早期城市規劃設立的主要幹道華盛頓街(Washington Street)和前街(Front Street)共線。該線於2005年改由馬凱特市府管理後解編。

該商業線在由密歇根州運輸部(Michigan Department of Transportation,MDOT)管理時屬於密歇根州高速幹線系統的一環;運輸部曾出於其職責監控來往41號國道商業線的運量並計算該商業線的年平均日運量。運輸部於2004年測量出該線於林肯大街和前街之間的年平均日車流量為10272次,為密歇根州高速幹線中運量最少者。該線在麥克萊倫大街和林肯大街之間的車流量最大,為19036次;前街則平均一天能達16309次的車流量[7]。該商業線並沒有被列入美國國家高速公路系統之中[8]。
