'''盐酸胍'''是[[胍]]的盐酸盐，通常可以缩写为GuHCl，有时也会写作GdnHCl或GdmCl。

==制备与结构==
盐酸胍可由[[氰胺]]和[[氯化铵]]在乙醇中于100 °C反应得到：<ref>L. F. Fieser, M. Fieser, in: ''Lehrbuch der organischen Chemie'', 3. Auflage, Verlag Chemie, 1957, Seite 267</ref>

盐酸胍属[[正交晶系]]，[[空间群]]为''Pbca''，其[[晶体结构]]包含[[胍]][[阳离子]]（C(NH<sub>2</sub>)<sub>3</sub><sup>+</sup>）和[[氯化物|氯]][[阴离子]]（Cl<sup>-</sup>），由N–H…Cl [[氢键]]连接。<ref>{{cite journal | first1= D.
