Multi-Higgs-boson production in {ital Z}{sup 0} decays is discussed in the context of low-energy supergravity models. For Higgs-boson masses lighter than about 20 GeV, {ital Z}{sup 0}{r arrow}{ital H}{sub 2}{sup 0}{ital H}{sub 2}{sup 0}{ital H}{sub 3}{sup 0} naturally has a branching ratio in the range 10{sup {minus}4}--10{sup {minus}6}. {ital Z}{sup 0}{r arrow}{ital H}{sub 2}{sup 0}{ital H}{sub 2}{sup 0}{ital l{bar l}}, where {ital l} is a neutral or charged lepton, has a branching ratio in the same range if {ital m}{sub {ital H}2}{lt}10 GeV. Detection of these processes will give information about the structure of the Higgs sector and about the {ital HHZZ} and {ital HHH} couplings.
