The Equivalent Lands were several large tracts of land that the Province of Massachusetts Bay made available to settlers from the Connecticut Colony after April 1716.
 This was done as compensation for an "equivalent" area of Connecticut-claimed territory which had been inadvertently settled by citizens of Massachusetts.
 The problem had arisen due to errors and imprecise surveys made earlier in the seventeenth century.
 The Equivalent Lands were never mapped.
