'''Arsenobetain''' adalah [[senyawa organoarsen]] yang banyak ditemukan pada [[ikan]].<ref>{{Cite journal|first1 = B.|last1 = Maher|title = Foreword: Research Front — Arsenic Biogeochemistry|journal = Environmental Chemistry|year = 2005|volume = 2|issue = 3|pages = 139–140|doi = 10.1071/EN05063}}</ref><ref>{{Cite journal|first1 = K.

Biokimia dan biosintesis betain mirip dengan [[kolin]].

Arsenobetain adalah senyawa umum dalam sistem biologi laut dan tidak seperti kebanyakan senyawa organoarsen seperti [[dimetilarsin]] dan [[trimetilarsin]], arsenobetain relatif tidak beracun.<ref>{{Cite journal|last1 = Bhattacharya|first1 = P.|last2 = Welch|first2 = A.

Sejak tahun 1920 telah diketahui bahwa ikan laut mengandung senyawa organoarsen, tetapi baru tahun 1977 struktur kimia senyawa yang paling melimpah, arsenobetain, ditemukan.<ref>{{Cite journal|author = Edmonds, J.
