教学生知识的人，尊称传授文化、技术的人，泛指在某方面值得学习的人。老师一词最初指年老资深的学者，后来把教学生的人也称为“老师”。《师说》中说：“师者，所以传道授业解惑也。”老师，是学生的学习引路人，是生活的指导者，人生的方向标。
我们平时虽然称呼学校里某教师为“某老师”，但这里的“老师”其实是教师这种职业，“传道授业解惑”是其基本功能。明清以来，一般称教师为“先生”；直至19世纪末，辛亥革命元老、中国现代教育奠基人何子渊等将西学（美式教育）引入中国，创办新式学校后，便开始在“学生操行规范”里面明确将“教师”称谓定义为“老师”。但，绝大部分学生约定俗成将“先生”改称为“老师”，则是从国民政府时代开始，并一直沿用至今。
事实上，现在“老师”的外延比“教师”的外延要大，除可以称“教师”为“老师”外，生活中我们还可以用“某老师”表示对别人的尊称，类似“老师傅”的简称。
“德高为范，技高为师”，从这个标准衡量，老师要先正己身，方可施教于人，“老师“两字可分解来看，中国历来推崇老子的思想和哲学，而老子尤其注重德行的修养，而这个“老”就代表了“德”，师者就不必细言了。
