RMS Mooltan was an ocean liner and Royal Mail Ship of the Peninsular and Oriental Steam Navigation Company (P&O). She was ordered in 1918 and completed in 1923. She served in the Second World War first as the armed merchant cruiser HMS Mooltan (F75) and then as a troop ship. She was retired from P&O service in 1953 and scrapped in 1954.

Mooltan was unusual in combining both quadruple-expansion steam engines and turbo-electric transmission. When completed in 1923 she had only her quadruple-expansion engines, but in 1929 turbo generators and electric propulsion motors were added alongside them to increase her speed.
