《麦琪的礼物》是美国著名文学家欧·亨利所写的一篇短篇小说。欧·亨利的小说构思新颖，诙谐幽默，常常有着出人意料的结局，在情理之中，又符合生活逻辑，因此常被称作“欧·亨利式结尾”。小说通过描写男女主人公在圣诞节前夕相互挑选礼物，交换礼物的一系列心理特点与斗争，反映出了贫民爱情中的真善美。但同时也反映出了当爱情面对现实时的两难选择。本文将从爱情与现实的矛盾，这个较为新颖的角度，通过分析当时的社会现状（其包括作者本身的一些经历，以及作品本身的特点），贫民爱情的研究以及艺术特色（结构的设置，修辞手法，细节描写）等方面，进行阐述。可以展现出喜剧式结尾的背后，其实反衬出了现实生活的辛酸与苦楚，以及贫民之间的爱情的真谛。
