John Cunningham Mclennan

John Cunningham Mclennan (Oktoba 14, 1867 – Oktoba 9, 1935) alikuwa mwanafizikia wa Kanada. 

Alizaliwa Ingersoll, Ontario. 

Alimaliza masomo yake kwenye chuo kikuu cha Toronto mnamo mwaka 1892 na alikuwa profesa wa fizikia huko kutoka mwaka 1907 hadi 1931.

Mchango wake mkubwa kwenye fizikia ulikuwa utafiti wake kuhusu ukinzani na upitishaji wa umeme katika vipitishi mbalimbali na spektra za elementi.
