Гармони́ческая фу́нкция  — вещественная функция U{displaystyle U} , определенная и дважды непрерывно дифференцируемая на евклидовом пространстве D{displaystyle D} (или его открытом подмножестве), удовлетворяющая уравнению Лапласа: Δ U=0, {displaystyle Delta U=0, } где Δ =∑ i=1n∂ 2∂ xi2{displaystyle Delta =sum _{i=1}^{n}{frac {partial ^{2}}{partial x_{i}^{2}}}}  — оператор Лапласа, то есть сумма вторых производных по всем прямоугольным декартовым координатам x i ( n = dim D - размерность пространства). Например, гармонической функцией является электростатический потенциал в точках, где отсутствует заряд.
