简称“郑”，史谓“天地之中”，古称商都，今谓绿城，河南省辖地级市、省会、特大城市 。郑州是华夏文明的重要发祥地、国家历史文化名城，是国家重点支持的六大遗址片区之一。
郑州大学是教育部与河南省人民政府部省合建高校、国家“双一流”建设高校、“211工程”建设高校。站在新的历史起点上，学校确立了综合性研究型大学办学定位，努力建设高水平研究型大学和区域性国家战略科技力量，提出了一流大学建设“三步走”发展战略，力争到本世纪中叶建成世界一流大学。
河南博物院创建于1927年，是我国首批中央地方共建国家级博物馆之一。院区占地面积126亩，建筑面积5.5万平方米。现有馆藏文物17万余件(套)，尤以史前文物、商周青铜器、历代陶瓷器、玉器及石刻最具特色。精品文物数量多、种类全、品位高、价值大，是见证中华文明发展轨迹，展示中国历史发展脉络的文化艺术宝库。
郑州黄河风景名胜区，又称郑州黄河水利风景区，位于河南省省会郑州市西北20千米处黄河之滨，南依岳山，北临黄河，历经四十年的开发建设，现已开放面积20多平方千米，形成了融观光旅游、休闲度假、科普教育、寻根祭祖、弘扬华夏文明为一体的大型风景名胜区。
烩面是郑州特色美食，有着悠久的历史。它是一种荤、素、汤、菜、饭聚而有之的传统风味小吃，以味道鲜美，经济实惠，享誉中原，遍及全国。另外一个闻名天下的小吃则是胡辣汤，大街小巷的各种早餐铺子都可以看到它的踪影，郑州王师傅胡辣汤味道突出胡椒的椒香，后味中有微微的辣，汤中的粉条、木耳、牛肉、面筋、豆皮让这碗貌不惊人的汤也随之生动起来。
