Quantum gravity is a field of theoretical physics that attempts to reconcile two of science's most successful theories—quantum mechanics (which describes the very small) and general relativity (which describes gravity and large-scale structures)—into a single, unified framework. Physicists pursue this because these two theories contradict each other in extreme conditions like those found at the center of black holes or at the moment of the Big Bang, so a unified theory is needed to understand physics in these regimes.

量子引力，是對引力場進行量子化描述的理論，屬於萬有理論之一。研究方向主要嘗試結合廣義相對論與量子力學，是當前物理學尚未解决的問題。當前主流嘗試理論有：超弦理論、迴圈量子重力理論。
