Although &lt;em&gt;Cakile maritima&lt;/em&gt; has a high antioxidant capacity, it is yet to be tested for the ability to inhibit the proliferation of cancer cells. &lt;strong&gt;Methods&lt;/strong&gt;: Solvent extracts prepared from &lt;em&gt;C. maritima&lt;/em&gt; plant material were analysed for antioxidant capacity by the DPPH free radical scavenging assay. Anti-proliferative activities against Caco&lt;sub&gt;2&lt;/sub&gt; and HeLa cancer cells were determined by an MTS based cell proliferation assay. Toxicity was determined by the Artemia franciscana bioassay. The most potent anti-proliferative extract (hexane) was further investigated using non-targeted GC-MS headspace analysis. &lt;strong&gt;Results&lt;/strong&gt;: Good DPPH radical scavenging activity was calculated for all &lt;em&gt;C. maritima&lt;/em&gt; extracts. The methanolic and ethyl acetate extracts had particularly strong antioxidant activity (IC&lt;sub&gt;50&lt;/sub&gt; of 4.7 and 3.4 μg/mL respectively). Interestingly, the hexane extract which had the lowest DPPH radical scavenging activity (IC&lt;sub&gt;50&lt;/sub&gt; 13.6 μg/mL), was the most potent inhibitor or Caco&lt;sub&gt;2&lt;/sub&gt; and HeLa carcinoma cell growth, with IC&lt;sub&gt;50&lt;/sub&gt;’s of 12 and 126 μg/mL respectively. The ethyl acetate extract was also a potent inhibitor of proliferation (IC&lt;sub&gt;50&lt;/sub&gt; values of 185 and 468 μg/mL against Caco&lt;sub&gt;2&lt;/sub&gt; and HeLa, respectively). The methanolic extract (IC&lt;sub&gt;50&lt;/sub&gt; values of 2261 and 2046 μg/mL against CaCo&lt;sub&gt;2&lt;/sub&gt; and HeLa respectively) displayed only moderate anti-proliferative activity, demonstrating that antioxidant activity did not correspond with anti-proliferative activity. All of the extracts were determined to be nontoxic in the Artemia franciscana bioassay, with LC&lt;sub&gt;50&lt;/sub&gt; values substantially &amp;gt;1000 μg/mL. Non-biased GC-MS headspace analysis of the &lt;em&gt;C. maritima&lt;/em&gt; hexane extract highlighted several interesting compounds that may contribute to the therapeutic bioactivities of the extract. &lt;strong&gt;Conclusion&lt;/strong&gt;: The lack of toxicity and the anti-proliferative activity of the hexane and ethyl acetate &lt;em&gt;C. maritima &lt;/em&gt; extracts against HeLa and Caco&lt;sub&gt;2&lt;/sub&gt; cancer cell lines indicates their potential in the treatment and prevention of some cancers.&lt;/p&gt;
