Bleckmar is a village administered by the Lower Saxon town of Bergen in the northern part of Celle district on the Lüneburg Heath in North Germany.

It lies about 3 kilometres (1.9 mi) north of Bergen on the B 3 federal road and has 464 inhabitants (2019).

Street names were not introduced in Bleckmar until 2001 after the majority of inhabitants voted in favour of them.

The River Meiße, which flows in a north–south direction through Bleckmar, was dammed to form a pond here used to power a corn mill.

Dageförde is a small farm hamlet where there are timber-framed farmhouses with ornate decorations, as well as typical heathland barns - the Treppenspeicher - from the 18th century.
