T57式3英寸火炮載具是一款美國自走炮。它使用了M3A3斯圖亞特式輕型坦克的底盤,是之前的T56的改進型。

1942年9月,美軍開始嘗試將3英寸火炮裝上改裝過的M3A3輕型坦克的底盤。這款火炮即T56式3英寸火炮載具。這款火炮的發動機被移動到了中部,而火炮和保護乘員的護盾則是後置。但是3英寸火炮對於T56來說過重,並對其性能造成了不利影響。T56還有另外一個問題就是乘員太少,炮組人員作業負擔極重使得射擊速度低下。因此衍生的T57是在T56基礎上嘗試進一步改良。它使用了一臺功率更強的發動機,並且去除了護盾,但測試結果依然不令人滿意。最終,美軍在1943年2月放棄了T57的研發計劃。[1][2]
