Meggitt PLC is a British engineering business specialising in aerospace equipment. It has its headquarters at Bournemouth Airport in Dorset. It is listed on the London Stock Exchange and is a constituent of the FTSE 250 Index.

The Company was established in the 1940s as a machine tool business based in Halifax known as Willson Lathes. It went public in 1947 and in 1964 acquired an engineering business in Dorset known as Meggitt. The Company subsequently changed its name from Willson Lathes to Meggitt Holdings.
