Report of Independent Auditors


To the Shareholders and Board of Trustees of
Dreyfus Investment Portfolios

In planning and performing our audit of the financial statements of
Dreyfus Investment Portfolios (comprising, respectively, Core Bond
Portfolio, Core Value Portfolio, Emerging Leaders Portfolio, Founders
Discovery Portfolio, Founders Growth Portfolio, Founders International
Equity Portfolio, MidCap Stock Portfolio, Small Cap Stock Index
Portfolio and Technology Growth Portfolio) for the year ended December
31, 2003, we considered its internal control, including control
activities for safeguarding securities, in order to determine our
auditing procedures for the purpose of expressing our opinion on the
financial statements and to comply with the requirements of Form N-SAR,
not to provide assurance on internal control.

The management of Dreyfus Investment Portfolios is responsible for
establishing and maintaining internal control. In fulfilling this
responsibility, estimates and judgments by management are required to
assess the expected benefits and related costs of controls.  Generally,
controls that are relevant to an audit pertain to the entity's
objective of preparing financial statements for external purposes that
are fairly presented in conformity with accounting principles generally
accepted in the United States.  Those controls include the safeguarding
of assets against unauthorized acquisition, use, or disposition.

Because of inherent limitations in internal control, error or fraud may
occur and not be detected.  Also, projection of any evaluation of
internal control to future periods is subject to the risk that it may
become inadequate because of changes in conditions or that the
effectiveness of the design and operation may deteriorate.

Our consideration of internal control would not necessarily disclose all
matters in internal control that might be material weaknesses under
standards established by the American Institute of Certified Public
Accountants. A material weakness is a condition in which the design or
operation of one or more of the internal control components does not
reduce to a relatively low level the risk that misstatements caused by
error or fraud in amounts that would be material in relation to the
financial statements being audited may occur and not be detected within
a timely period by employees in the normal course of performing their
assigned functions.  However, we noted no matters involving internal
control and its operation, including controls for safeguarding
securities, that we consider to be material weaknesses as defined above
as of December 31, 2003.

This report is intended solely for the information and use of management
and the Board of Trustees of Dreyfus Investment Portfolios and the
Securities and Exchange Commission and is not intended to be and should
not be used by anyone other than these specified parties.
