One night, the Nohara family were enjoying a pleasant dream, when suddenly a big fish appeared in their dreams and ate them. The next morning, Hiroshi read in the newspaper that everybody in another town had the same nightmare as him, but it seemed to have ended. But Hiroshi also heard the same dream from Misae, Shinnosuke, Himawari and even Shiro. They were surprised and thought if the same thing is happening in Kasukabe too. In kindergarten, on telling others about his nightmare, Shinnosuke was surprised to know that everybody too had the same dream. Then a mysterious girl named Saki was transferred to Futaba Kindergarten and joined Shinnosuke's class. Everyone in the class, including the rather inactive Bo-chan, were all excited and happy on seeing her. But Saki had a cold attitude and didn't get along well.

小丸子是一名小学二年级的女生，她活泼、好动、懒惰、什么事情都拖到最后一刻才做、学习不认真、成绩平平、经常和姐姐斗气、爱幻想、做事没恒心……在小丸子身上我们或多或少都看到了自己童年的影子。如果小丸子算是一个“怪人”的话，那么她的周围可谓“怪人”多多，有点神经质的班长丸尾同学、权利欲极强的女副班长、经常和小丸子一起疯的爷爷，讨人厌的宾治同学等等，这群性格各异、精力充沛的小孩、大人们，每天都在演绎着生活的趣事，伴随着小丸子一天天长大。

小新今年5岁了，不要以为他是那种懵懂无知的小孩，他其实人小鬼大，喜欢漂亮的姐姐，收养了一条棉花糖一样的流浪狗——小白，还经常讲些无厘头的黄色笑话。小新的妈妈美伢是一个全职主妇，粗心而又有点神经质的她经常被小新捉弄得七窍生烟，爸爸野原亦经常被这两母子搞得晕头转向。
《蜡笔小新》的作者以一个5岁小童的眼光，40岁的成年人的心态去观察这个大千世界，看到了许多光怪陆离的景象，小新一家的幽默故事亦由此产生。
