Lieutenant-General Robert Lawson (died 26 February 1816) was a British Army officer who served in the Royal Artillery during the American War of Independence and the Egyptian Campaign.

There is little information respecting his services during the American war, but in the Royal Military Repository, Woolwich, was placed a model of "a field-carriage for small mortars to be used occasionally as howitzers", which is stated to have been invented and used by him at the siege of Charleston, and another showing his plan of mounting mortars for firing at various elevations, "experimented and approved at New York in 1780".

With some difficulty the temporary rank of brigadier-general, which had been accorded to officers of like standing of other arms, was obtained for him; during the campaign he was promoted to colonel in 1801.

His professional memoranda on the operations, were published by the Royal Artillery Institute, Woolwich, for the instruction of gunners of later generations.

[1] During the invasion alarms of 1808 a project for the defence of London was started, which had the support of prime minister William Pitt, and Lawson, with the rank of brigadier-general, was given responsibility for the selection of sites for the batteries, but no practical results followed.
