Robert Henderson (Bob) Croll (5 January 1869 – 18 October 1947) was an Australian writer, poet, bushwalker, and public servant. The Australian Dictionary of Biography (ADB) characterises him as noteworthy for his "diverse contribution to cultural and intellectual life," with his prominence in art curation, writing and editing poetry, engaging in and journalling about athletics (specifically cross country running and bushwalking, for which the ADB credits him as doing "possibly...more than anyone else in his time to encourage").
