A sleeve and plug launcher for launching a sleeve and plug down an oil or gas well includes sleeve and plug holders, a support plate beneath the open bottoms of the sleeve and plug holders, an aperture positioned in the support plate and a sleeve and plug discharge connectable to a well head of a well and positioned below the aperture. When one of the sleeve and plug holders stops over the aperture in the support plate, a sleeve and plug in the sleeve and plug holders drops through the aperture and is directed into a wellhead by the sleeve and plug discharge.
