Jeshi la majini au Jeshi la wanamaji ni kitengo cha pekee cha jeshi la mataifa mengi kilicho tayari kushindana na maadui kwenye maji hasa baharini.
Linajumlisha askari, manowari, meli za kuasaidia manowari, mabandari ya pekee na vituo vingine na pia eropleni za vita ya bahari.
Ni hasa nchi zenye pwani la bahari ambako kuna jeshi la pekee la wanamaji. Chanzo katika historia yalikuwa majeshi ya wanamaji ya Karthago, Ugiriki ya Kale na Dola la Roma. Tangu karne ya 19 Uingereza ilikuwa na jeshi la wanamaji kubwa duniani, na katika karne ya 20 nafasi yake ilichukuliwa na wanamaji wa Marekani hasa, lakini pia wa Urusi.
