A rare earth tungsten alloy crucible and a manufacturing method thereof. The rare earth tungsten alloy crucible comprises, in mass percent, 1.3-2.5% of lanthanum oxide and 97.5-98.7% of tungsten. The manufacturing method comprises the following steps : step (1) : preparing a rare earth tungsten alloy, step (2) : preparing a rare earth tungsten alloy crucible blank, and step (3) : preparing a finished product. The rare earth tungsten alloy crucible has excellent high-temperature mechanical properties and high creep resistance, tensile strength, toughness, and durability, thereby reducing the usage cost.
