The present invention relates to a recombinant microorganism for producing putrescine or ornithine and a method for producing putrescine or ornithine using the same. Specifically, the present invention relates to: a Corynebacterium sp. microorganism producing putrescine or ornithine, which is engineered to weaken a transcriptional regulator of sugar metabolism (SugR), enhance citrate synthase (GltA), or perform both; and a method for producing putrescine or ornithine using the same. La presente invención se refiere a un microorganismo recombinante de producción de putrescina u ornitina, y un procedimiento de producción de putrescina u ornitina utilizando el mismo. Específicamente, la presente invención se refiere a un microorganismo del género Corynebacterium capaz de producir putrescina u ornitina, en el que se debilita una actividad del regulador transcripcional del metabolismo de azúcar (SugR), se potencia una actividad de citrato sintasa (GItA) o se aplican ambos; y un procedimiento de producción de putrescina u ornitina utilizando el mismo.
