网足虫属（学名：Gromia）是丝足虫门的一个属，为单细胞生物，栖息在淡水或海水中，本属生物形似变形虫，有一蛋白质组成的蜂窝状壳体（英语：Test (biology)）将细胞质包覆，并有许多伪足从壳体表面的孔洞中伸出，可互相交连形成网状结构^[1]，用以爬行移动^[2]。本属物种的直径介于0.4－30毫米间，细胞质中具有Stercomata（英语：Stercomata）（排泄物）与矿物颗粒^[3]，壳体形状多变，有球型者（G. oviformis），也有梨形者（G. pyriforminis），常作为本属物种的分类依据。本属生物可行无性生殖与有性生殖^[4]。

本属最早被发现的物种为G. oviformis，于1835年在英国海边的潮间带被发现^[5]，1990年代起开始有多种深海中的网足虫被发现，包括生存在4392公尺深处者^[3]，深海的网足虫可能在碳循环^[3] 与氮循环（反硝化反应）^[6]中扮演一定角色。有研究显示本属的一深海物种圆球网足虫可在海床上留下爬痕，与复杂多细胞动物所留下的遗迹化石类似，使考古学家怀疑此类化石是否能当作多细胞动物存在的依据^[7] 。
