Two are taking place – at Sea View Walk in Skegness and Miners Walk in Winthorpe.
They are organised by the Skegness We Want Coastal Access For All group to prepare for the Spring Bank Holiday next weekend.
Anyone interested in taking part is asked to meet at 10am. The beach cleans are expected to last a couple of hours.
This week the central beach in Skegness was awarded the Blue Flag for cleanliness.
