Distinctive Software (DSI) was a Canadian video game company headquartered in Burnaby, British Columbia, and was established by Don Mattrick and Jeff Sember in 1982.

During the decade of 1980 and in the early 1990's the studio was know for various sports games, as well as racing games which included Stunts and the first installments in the Test Drive series; Test Drive and The Duel: Test Drive II.

The studio lost the rights to make Test Drive games after a lawsuit by Accolade, as Distinctive Software had used software libraries which they created for Test Drive II, a game published by Accolade, for a MS-DOS port of Outrun, a game published by Sega. Distinctive Software won the lawsuit, but the rights to make the Test Drive games without the source code were transferred to Accolade.

Distinctive Software was then acquired by Electronic Arts in 1991 and renamed to EA Canada. The studio would then develop the first installments in the Need for Speed series, as well as various games released under the EA Sports label.
