槟城香火最旺的神明之一大伯公或称福德正神，是管理土地之神，也就是土地公。福建人、潮州人、客家人皆称为「伯公」，而大多数老槟城家里都有供奉大伯公，保佑一家男女老少家居平安、和气生财、健康如意。中国自古代就已经祭地神，人们认为有土地才能够生长五谷，有了五谷方能养活人类。所以对于滋养万物的土地要时刻感恩土地。
全马各地，无论是市内还是郊外，到处都可看到庙内、义山、宗祠、社、住家、商店、工厂有供奉地主公、土地公、大伯公或福德正神。除此之外，华人义山的入口处会有大伯公庙或福德祠，各墓旁会有后土。土地公、地主公、后土、大伯公或福德正神就是负责管理与保护不同范围、不同地点或不同建筑的土地神。而二月初二、八月十五就是土地诞，也就是大伯公福德正神诞。
