The headwaters of the river rise in the Philips Range near Qodesh then flow in a south-easterly direction parallel with the King Leopold Range and past Mount House, Mount Clifton and Mount Hamilton before merging with the Fitzroy River near Fitzroy Bluff.
The Adcock has three tributaries; Throssel River, Annie Creek and Walsh Creek.
The first European to discover the river was Frank Hann in 1898, who named the river after Charles and William Adcock of Derby: Hann explained, "Messrs Adcock Bros of Derby were very kind to me and provided exceedingly reasonable in the important matter of a supply of rations."
