PROSPECTUS

<div align='center'>Incannex Healthcare Inc.

75,902,171 Shares of Common Stock</div>

This prospectus relates to
the offer and sale by the selling stockholders named in this prospectus, and any pledgee, donee, transferee or other successor in interest,
of up to an aggregate of 75,902,171 shares (the “Shares”) of common stock, par value $0.0001 per share, of Incannex Healthcare
Inc. (the “Common Stock”).

We are registering for resale
(i) 9,687,045 shares of Common Stock held by the selling stockholders, (ii) 1,887,045 shares of Common Stock issuable upon the exercise
of pre-funded warrants (the “Pre-Funded Warrants”) to purchase shares of Common Stock held by certain selling stockholders,
and (iii) 64,328,081 shares of Common Stock issuable upon the exercise of Series A common stock warrants (the “Series A Warrants”
and together with the Pre-Funded Warrants, the “Warrants”) to purchase shares of Common Stock held by the selling stockholders.

The Series A Warrants are
not currently exercisable and will be exercisable following the date of Stockholder Approval (as defined in the Section titled “Prospectus Summary – 2025 Private Placement” on page 1 of this prospectus). In the event that we are unable to obtain the required
Stockholder Approval for the Series A Warrants, such warrants will not be exercisable and therefore have no value.

Our registration of the
Shares covered by this prospectus does not mean that the selling stockholders will offer or sell any of the Shares. The selling
stockholders may sell any, all or none of the Shares offered by this prospectus and we do not know when or in what amount the
selling stockholders may sell their Shares hereunder following the effective date of this registration statement. The selling
stockholders named in this prospectus, and any pledgee, donee, transferee or other successor-in-interest, may offer the shares from
time to time through public or private transactions at prevailing market prices, at prices related to prevailing market prices or at
privately negotiated prices. For further information regarding the possible methods by which our Common Stock may be distributed,
see “Plan of Distribution” beginning on page
