Ladies and Gentlemen:

On behalf of Legg Mason Partners Equity Trust (the “Trust”), and pursuant to Rule 497(j) under the Securities Act of 1933, as amended (the “1933 Act”), I hereby certify that the form of Prospectus and Statement of Additional Information for Legg Mason Partners All Cap Fund, a series of the Trust, that would have been filed under Rule 497(c) would not have differed from those filed as part of Post-Effective Amendment No. 73 to the Trust’s Registration Statement on Form N-1A filed on August 27, 2007. That Post-Effective Amendment became effective automatically pursuant to Rule 485(b) under the 1933 Act on August 28, 2007.

If you have any questions or comments, please do not hesitate to call me at (212) 728-8558.

Very truly yours,
