副狒（Parapapio）是一属史前的狒狒，外表像森林的白睑猴。副狒与狒狒不同的是，牠的眉嵴很窄，没有犬齿窝或矢状嵴，只有少许两性异形。^[1]

现时已知有四个副狒的物种，包括P. jonesi、P. whitei、P. broomi及P. antiquus，但这些分类却仍有一些争议。传统上，这些物种都只在臼齿的大小来作出分野，如P. jonesi的臼齿最细小，P. whitei的则最大，但是P. broomi的臼齿差异却与这两种副狒一致。^[2]P. jonesi的鼻端较P. whitei的更为方形，但较Pp. broomi为圆。这些分野实在太微小，故有需要更完善的分类条件。^[1]

虽然一些学者指副狒分类有问题，但却不赞成重新分类。这是由于P. broomi与P. jonesi的平均牙齿大小或同位素特征没有明显差异^[3]，这显示牠们可能是两性异形的同一物种。^[4]但是P. broomi及P. whitei的差异范围重叠，并且没有统计学上的差异^[5]，故有建议指牠们其实是同一物种。^[2]更复杂的是，P. jonesi的标本在面部特征上都与其他副狒有明显不同。
