The name Lachelle is a feminine given name of French origin. It is a variant spelling of the French name Rachelle, which itself is derived from the Hebrew name Rachel. Rachel can be traced back to the Biblical Hebrew name רָחֵל (Rachel), meaning "ewe" or "female sheep."

The earliest known recorded use of the name Lachelle dates back to the late 1960s, but it remained relatively rare until the 1980s and 1990s when it grew in popularity as a baby name.

One of the earliest notable individuals to bear the name Lachelle was Lachelle Crosse, an American singer and actress born in 1957. She had a successful career on Broadway and appeared in several films and television shows.
