六亚甲基三过氧化二胺（Hexamethylene triperoxide diamine，HMTD）是一种有机过氧化物起爆药，由Legler在1885年首先制得。

作为一种有机过氧化物，由于分子内过氧键的存在，HMTD对摩擦、火焰及物理冲击较敏感，但稳定性和TATP等相比尚佳。紫外线的照射与金属离子的存在都将敏化HMTD。不含酸、碱和金属离子、纯净的HMTD有着良好的化学稳定性且不易升华。

HMTD由过氧化氢与乌洛托品在柠檬酸或硫酸催化下于水溶液中反应制得，合成较雷汞简便，在起爆力、稳定性与成本方面亦有优势，但起爆效果不如叠氮化铅。曾用于矿井中的爆破，但已被特屈儿等更稳定的炸药所取代。

Hexamethylene triperoxide diamine (HMTD) is a high explosive organic compound. The theorized structure lent itself well to acting as an initiating, or primary explosive. While still quite sensitive to shock and friction, it was relatively stable compared to other initiating explosives of the time, such as mercury fulminate, and proved to be relatively inexpensive and easy to synthesise. As such, it was quickly taken up as a primary explosive in mining applications. However, it has since been superseded by even more stable compounds such as tetryl.
