The invention provides a rock sample water content observation method and device. The rock sample water content observation method comprises the following steps: contacting a rock sample with water-sensitive test paper; acquiring an image of a contact area of the rock sample and the water-sensitive test paper, and calculating the total area S of the contact area; acquiring an image of a color developing region of the water-sensitive test paper, and calculating the area S1 of the color developing region; and calculating the percentage of the area S1 of the color developing region and the total area S of the contact region, and analyzing the water content of the rock sample according to the percentage. Compared with the prior art, the rock sample water content observation method suitable for the field is established by utilizing the sensitivity of the water-sensitive test paper and the convenience of image acquisition and processing, has the advantages of simplicity and convenience in operation, short observati
