Lynds' Catalogue of Bright Nebulae (LBN) 437 is a molecular cloud at the edge of the large emission nebula Sh2-126 and the star forming region Lacerta OB1 in the constellation Lacerta.

The densest part of LBN 437 is associated with some bright young stars, among which stands out LkHα 233, also known by the acronym of variable star V375 Lacertae: an Ae / Be Herbig object of thirteenth magnitude, which shows strong Hα-emission. This star is also the main responsible for the excitation of some bipolar Herbig-Haro-Objects.
