A magnetic tape cartridge includes a cartridge casing formed by upper and lower casing halves and a single reel around which a magnetic tape is wound and which is contained in the cartridge casing for rotation. A slide door for opening and closing a tape outlet opening is mounted on the cartridge casing to be linearly slidable along a door passage between a closing position where it closes the tape outlet opening and an opening position where it opens the tape outlet opening. A door spring for urging the slide door toward the closing position and holding the same in the closing position is disposed on the door passage.
