Platja de s'Home Mort, Mediterranean beach in Santa Margalida, Spain.

Platja de s'Home Mort is a beach on the northeastern coast of Mallorca with a sandy shoreline and natural surroundings. The water starts shallow at the edge and gradually deepens as you enter.

The name, meaning "beach of the dead man", is documented in Catalan and German sources but the origin of the name is not recorded. The beach lies within Son Serra de Marina, a settlement of Santa Margalida; the coast road from the MA-12 is named Avinguda del Talaiot de sa Nineta after a prehistoric talayot standing at the junction.

The name means "beach of the dead man" in Catalan. The beach is also often called Platja de Son Serra de Marina, though a separate beach further east carries that name. The seafront street behind the dunes is lined with one- and two-storey houses, many occupied only part of the year.

The beach lies directly east of Son Serra de Marina's yacht harbour, between the rocks of Es Mollet at Punta de Sa Barraca and Es Corral des Marbres. Reach the village by the road branching north at kilometre 14.4 of the MA-12 between Artà and Alcúdia, then follow Avinguda del Talaiot de sa Nineta past the talayot to the harbour. A coastal road runs behind the dunes.

The beach is often called Platja de Son Serra de Marina, though a separate beach further east bears that name. It lies directly east of the Es Mollet de Son Serra de Marina harbour, below the Punta de Sa Barraca.
