順磁共振（Paramagnetic Resonance）是研究含有未配對電子物質的一種磁共振技術，屬于電子順磁共振（Electron Paramagnetic Resonance, EPR）或電子自旋共振（Electron Spin Resonance, ESR）的範疇。其原理基于順磁性物質中的未配對電子在外加磁場作用下發生能級分裂，并通過吸收特定頻率的電磁波能量實現共振躍遷。共振條件由公式表達為：
$$
h u = gmu_B B
$$
其中，(h)為普朗克常數，( u)為電磁波頻率，(g)為朗德因子，(mu_B)為玻爾磁子，(B)為外加磁場強度。
該技術廣泛應用于化學、材料科學和生物學領域，例如研究自由基、過渡金屬離子、催化劑活性中心及生物大分子中的未配對電子結構。其高靈敏度特性（可檢測低至納摩爾濃度的樣品）使其成為表征材料磁性和電子态的重要工具。
在實驗方法上，順磁共振通常使用微波波段（X波段或Q波段）激發樣品，并通過檢測吸收信號強度與磁場強度的關系獲得譜圖，進而分析樣品的局部對稱性、自旋密度分布及動力學行為。
