再保险，英文表达为reinsurance，亦称“分保”。保险人在原保险合同的基础上，通过签订分保合同，将其所承保的部分风险和责任向其他保险人进行保险的行为。再保险的基础是原保险，再保险的产生，正是基于原保险人经营中分散风险的需要。

在再保险交易中，分出业务的公司称为原保险人（Original insurer）或分出公司（Ceding company），接受业务的公司称为再保险人（Reinsurer），或分保接受人或分入公司（Ceded company）。

重复保险，英文表达为multiple insurance/overlapping insurance/concurrency/double insurance/concurrent insurance，亦称“复保险”。是指投保人对同一保险标的、同一保险利益、同一保险事故，在同一保险时期分别向两个或两个以上的保险人订立保险合同（实际上如上已经是重复保险），且（或）保险金额总和超过保险价值的保险（各国的保险法对重复保险的定义不同，实际上这句只是定义了重复保险是否为超额保险，据此可以将重复保险分为“超额复保险”与“未超额复保险”）。
