Abstract : In this paper, we have characterizations of almost P-spaces which are analogous characterizations of P-spaces and we will show that if X is an almost P-space such that it is C$^*$-embedded in every almost P-space in which X is embedded, then $\mid \upsilon \text{X}-\text{X} \mid \le 1$ and that if $\mid \upsilon \text{X}-\text{X} \mid \le 1$ and $\upsilon$X is Lindel\"of, then for any almost P-space Y in which X is dense embedded, then X is C$^*$-embedded in Y.
Keywords : C$^*$-embedding, almost $P$-spaces
