Sir Robert Hormus Kotewall CMG (Chinese: 羅旭龢; 1880–1949) was a British Hong Kong businessman, civil servant and legislator.

He was the son of Hormusjee Rustomjee Kotewall, an Indian Parsi, and Cheung A-cheung.

After Sir Mark Young was restored as the governor of Hong Kong, Kotewall submitted a 66-page report explaining the causes and consequences of his actions as a Chinese representative during the Japanese occupation period, but it was not accepted by the British government.

Although he was not prosecuted for treason, he was still blacklisted by the Hong Kong government and for the rest of his life would never again be appointed to official positions.

At the same time, he was also listed as one of the traitors sought by the Guangdong government of the Republic of China, so he rarely subsequently participated in public life.
