美国的浪漫主义文学深受西欧浪漫主义文学的影响。19世纪上半叶，美国资本主义迅速发展，民族意识和爱国热情高涨，摆脱英国文学的束缚、重视人的精神创造和追求自由的超验主义蔚为大观，至此美国浪漫主义文学开始蓬勃发展。因此其作品从内容到形式都具有鲜明的民族特色。浪漫主义强调人的精神作用和直觉的意义，认为自然界充满灵性，人应该回归自然，主张艺术要使读者获得刺激而达到灵魂的升华。
美国现实主义注重事实或现实；不受理想主义、臆测或感伤主义影响的客观过程；客观地而不凭感情地去处理思想和行动，反对一切不切实际或空想的性格。现实主义抛弃早期廉价的乐观主义，开始表现社会矛盾。在欧洲现实主义与自然主义文学的影响下，美国的现实主义从许多方面反映社会消极的一面。
美国现实主义各具艺术特色，逼真，反映广阔的社会图景，引进印象主义手法，甚至开辟了美国式短篇小说的途径，对美国文学的成熟作出了伟大的贡献。
