Hwang Ui-jo scored the only goal as Norwich beat QPR to claim back-to-back wins for the first time since August.
The South Korea striker, on loan from Nottingham Forest, collected Gabriel Sara's ball and fired home midway through the first half.
Hwang's winner ended a run of three consecutive defeats at Carrow Road, while QPR are without win in 11 games.
The Canaries climb to 13th place, with Rangers still 23rd and six points adrift of safety.
While Rangers enjoyed early possession, they were unable to convert that into scoring opportunities and only Steve Cook's goalline clearance denied Norwich's Jack Stacey as his looping effort sailed over Asmir Begovic.
